International Law

 Chapter 1

THE NATURE OF INTERNATIONAL LAW

What is international law?

The traditional definition of international law is that it is a body of rules and 

principles of action which are binding upon civilized states in their relations to one 

another. States are the sole actors in this definition and, in the past, public 

international law dealt almost exclusively with regulating the relations between 

states in diplomatic matters and in the conduct of war. Today, sovereign states 

remain as the principal subjects of international law; but they are now joined by 

international organizations and even by individuals.' Thus, the Restatement (Third) 

of Foreign Relations Law of the United States, which U.S. courts generally 

consider as the most authoritative work on the subject, defines international law as 

the law which deals “with the conduct of states and of international organizations 

and with their relations inter se, as well as with some of their relations with 

persons, whether natural or juridical.”2

Scope of international law.

The expansion of the scope of international law is nothing short of 

revolutionary: New subject matters are being added, new subjects of international 

law are being recognized, non-Western states are flooding into the community of 

nations, political and social principles are changing, international organizations are 

assuming new roles. This is being affected by various factors: rapid changes in 

technology, the multiplication of the number of states with differing backgrounds 

and achieving loose forms of cooperation, fear of war, rising demands for social 

reform.

'Subjects of international law will be treated at greater length in Chapter 5.

2 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The topics that are covered by international law today include the regulation 

of space expeditions, the division of the ocean floor, the protection of human rights, 

the management of the international financial system, and the regulation of the 

environment. Beyond the primary concern for the preservation of peace, it now 

covers all the interests of contemporary international and even domestic life.

Is international law a law?

The question is sometimes asked whether international law is indeed law. 

The basic challenge to international law as law is the claim that there can be no law 

binding sovereign states. Moreover, there exists no international legislative body. 

There is, of course, the General Assembly of the United Nations; but its resolutions 

are generally not binding on anybody. There is no international executive. The 

Security Council was intended to be that entity but it is often effectively hamstrung 

by the veto power. Neither is there a central authority that can make judgments 

binding on states. The International Court of Justice can bind states only when 

states consent to be bound. Moreover, national officials tend to find justification for 

whatever they do. Psychologically too, the allegiance to one’s sovereign state can 

be very strong to the point of defying reason. When the chips are down, national 

policy or interest is often preferred over international law. Enforcement of 

international law is a real problem for several reasons. Frequently, there is no 

assured procedure of identifying violation. Even the powers of the UN have 

reference largely to lawbreaking that takes the form of an act of aggression or 

threat to peace. But there are many violations of international law which are not of 

this nature. Most of the time, all the UN can do is censure. For these reasons, it is 

said that what is called international law is not law because it is commonly 

disregarded.

These objections are based on an exaggerated notion of sovereignty as 

embodying an individualist regime. This, however, is not the reality. The reality is 

social interdependence and the predominance of the general interest. The reality is 

that States are bound by many rules not promulgated by themselves. As Henkin 

observes, “It is probably the case that almost all nations observe almost all 

principles of international law and almost all of their obligations almost all of the 

time.”3

3Henkin, HOW NATIONS BEHAVE 42.

CHAPTER 1

THE NATURE OF INTERNATIONAL LAW

Brierly adds: “The ultimate explanation of the binding force of all law is that man, 

whether he is a single individual or whether he is associated with other men in a

state, is constrained, in so far as he is a reasonable being, to believe that order and 

not chaos is the governing principle of the world in which he lives.”4

In the ultimate analysis, although the final enforcer is power, fundamentally, 

there is a general respect for law because of the possible consequences of defiance 

either to oneself or to the larger society.

Some theories about international law.

If international law is a law, what is its theoretical basis or what makes it a 

law?

Command theory. In the view of John Austin, a renowned legal philosopher, 

law consists of commands originating from a sovereign and backed up by threats of 

sanction if disobeyed. In this view, international law is not law because it does not 

come from a command of a sovereign. Neither treaties nor custom come from a 

command of a sovereign. This theory, however, has generally been discredited. The 

reality is that nations see international law not as commands but as principles for 

free and orderly interaction.

Consensual theory. Under this theory, international law derives its binding 

force from the consent of states. Treaties are an expression of consent. Likewise, 

custom, as voluntary adherence to common practices, is seen as expression of 

consent.5

In reality, however, there are many binding rules which do not derive 

from consent.

Natural law theory. The natural law theory posits that law is derived by 

reason from the nature of man International law is said to be an application of 

natural reason to the nature of the state-person. Although the theory finds little 

support now, much of customary law and what are regarded as generally accepted 

principles of law are in fact an expression of what traditionally was called natural 

law.

Some dissenters, however, see no objective basis for international law. They 

see international law as a combination of politics, morality and self-interest hidden 

under the smokescreen of legal language.

4Brierly , THE LAW OF NATIONS 55-56

treaties and custom will be treated in subsequent chapters.

4 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

In the ultimate analysis, however, the best answer is pragmatic. 

Fundamentally, there is a general respect for law and also there is concern about the 

consequences of defiance either to oneself or to the larger society. International law 

is law because it is seen as such by states and other subjects of international law.

Public and private international law.

A distinction should be made between public international law, sometimes 

referred to only as international law and which is the subject matter of this book, 

and private international law, more commonly called conflict of laws. Public 

international law governs the relationships between and among states and also their 

relations with international organizations and individual persons. Private 

international law is really domestic law which deals with cases where foreign law 

intrudes in the domestic sphere where there are questions of the applicability of 

foreign law or the role of foreign courts.

Brief historical development of international law.

From Ancient law to the League of Nations

What may be called ancient international law governed exchange of 

diplomatic emissaries, peace treaties, etc., in the world of ancient Romans and even 

earlier. There is evidence of treaties concluded between Jews and Romans, Syrians 

and Spartans. The progressive rules of jus gentium, seen as a law “common to all 

men,” became the law of the vast Roman empire.

Modem international law began with the birth of nation-states in the 

Medieval Age. The governing principles were derived from Roman Law or Canon 

Law which in turn drew heavily from natural law. Hugo Grotius, Dutch, is 

considered father of modem international law. He authored De Jure Belli ac Pads.

What he called the “law of nations” was later given the name of “international law” 

by the British philosopher Jeremy Bentham.

Before Grotius was Alberico Gentili, Oxford Professor of Roman Law (De 

Jure Belli) and the Spanish theologian Francisco de Vitoria and the Jesuit 

theologian Francisco Suarez; Samuel Pufendorf, German (De Jure Naturae 

Gentium); Emmerich de Vattel, Swiss (The Law of Nations). These were generally 

natural law people.

CHAPTER 1

THE NATURE OF INTERNATIONAL LAW

The positivist approach reinterpreted international law not on the basis of 

concepts derived from reason but rather on the basis of what actually happened in 

the conflict between states. With the emergence of the notion of sovereignty of 

states came the view of law as commands originating from a sovereign and backed 

up by threats of sanction if disobeyed. In this view, international law is not law

because it does not come from a command of a sovereign. Neither treaties nor 

custom come from a command of a sovereign.

The following are some of the significant milestones in the development of 

international law:

(a) The Peace of Westphalia, which ended the Thirty Years War 

(1618-1648) and established a treaty based framework for peace cooperation. 

(It was at this time that pacta sunt servanda arose.)

(b) Congress of Vienna (1815), which ended the Napoleonic Wars 

and created a sophisticated system of multilateral political and economic 

cooperation.

(c) Covenant of the League of Nations (1920) which included the 

Treaty of Versailles which ended World War I.

In the aftermath of World War I, the victors decided to create an institution 

designed to prevent the recurrence of world conflagration. Thus, the League of 

Nations was bom. Its membership consisted of 43 states which included the five 

British dominions of India, Canada, South Africa, Australia and New Zealand. The 

United States did not join.

The League created the Permanent Court of International Justice.

From the end of World War II to the end of the Cold War

The League of Nations failed to prevent World War II. Thus, the formulation 

of a new avenue for peace became the preoccupation of the victors. Hence was 

founded the United Nations in 1945. This marked the shift of power away from 

Europe and the beginning of a truly universal institution. The universalization was 

advanced by decolonization which resulted in the expansion of the membership of 

the United Nations. New states, carrying a legacy of bitterness against colonial 

powers, became members of the UN.

6 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

It was during this period that three major groupings of states arose.

The Western states, although they were not all completely of one mind, 

formed one group. Some remained satisfied with the status quo while others were 

more open to Third World demands and supported social and legal changes. As to 

international legislation, however, they insisted on two points. First, legal 

provisions miust'be clear and precise. Second, any substantive rule must be 

accompanied by an implementation mechanism that can spot and correct 

violations.

Another grouping consisted of the socialist states led by the Soviet Union. 

They formed the “socialist camp.” They sought to avert Western intrusion into 

domestic affairs even as they sought relatively good relations with the West for the 

sake of economic and commercial interchange. They also sought to convert 

developing nations to their ideology.

The third group, the developing countries, formed the overwhelming 

majority. The group consisted mainly of former colonies suffering from 

underdevelopment together with newly industrializing countries such as the 

Philippines, Malaysia, Thailand, Singapore, and South Korea who had earned their 

independence through armed or political struggle while remaining under the 

influence of Western or socialist ideas.

This was the Cold War period which succeeded in maintaining peace 

through the balancing of the two super powers, the United States and its allies on 

the one hand and the Soviet Union.

The end of the Cold War

The dissolution of the Soviet Union resulted in the end of the Cold War with 

the re-emergence of international relations based on multiple sources of power and 

not mainly on ideology. Many of the Baltic states were restored to statehood. 

Yugoslavia collapsed and fragmented. The newly bom Russian Federation did not 

inherit the Soviet Union’s position as a superpower.

At present there is only one super power, the United States, politically and 

ideologically leading the western states. The United States acts both as world 

policeman (but in an obviously selective manner as dictated by its own interests) 

and also as global mediator.

CHAPTER 1

THE NATURE OF INTERNATIONAL LAW

Meanwhile, socialist countries are no longer united with some of them 

depending on the support of Western states.

For their part, the developing countries seem to have veered away from 

ideological orientation and towards market orientation instead and towards fighting 

poverty and backwardness.

As for the United Nations, it seems to have declined as an international 

agency for the maintenance of peace.

Chapter 2

THE SOURCES OF INTERNATIONAL LAW

What sources are.

The task of ascertaining what the laws are in the domestic sphere is a 

relatively simple matter. Domestic laws are found in statute books and in 

collections of court decisions. It is an altogether different matter with international 

law. In the absence of a centralized legislative, executive and judicial structure, 

there is no single body able to legislate and there is no system of courts with 

compulsive power to decide what the law is nor is there a centralized repository of 

international law. Thus, there is the problem of finding out where the law is. This 

problem is exacerbated by the anarchic nature of world affairs and the competing 

sovereignties. Nevertheless international law exists and there are “sources” where, 

with some effort, the law can be found.

Sources are often classified into formal sources and material sources.

Authors, however, differ in defining these concepts. Formal sources can refer to 

the various processes by which rules come into existence. Thus, for instance, 

legislation is a formal source of law. So are treaty making and judicial decision 

making as well as the practice of states. Material sources, on the other hand, are 

not concerned with how rules come into existence but rather with the substance and 

content of the obligation. They identify what the obligations are. In this sense, state 

practice, UN Resolutions, treaties, judicial decisions and the writings of jurists are 

material sources in so far as they identify what the obligations are. They are also 

sometimes referred to as “evidence” of international law.

The doctrine of sources lays down conditions for verifying and ascertaining 

the existence of legal principles. The conditions are the observable manifestations 

of the “wills” of States as revealed in the processes by which norms are formed —

that is, treaty and state prac8 

CHAPTER 2

THE SOURCES OF INTERNATIONAL LAW

tice accepted as law. The process of verification is inductive and posi- tivistic. It is 

the process of finding what laws the states themselves have created and what laws 

they are willing to place themselves under. It is a manifestation of the fact that 

international law is characterized by individualism.

It is interesting, however, that the most widely accepted statement of the 

“sources” of international law, that is, Article 38(1) of the Statute of the 

International Court of Justice, does not speak of sources. Rather, Article 38 is 

primarily a directive to the Court on how it should resolve conflicts brought before 

it. Article 38 says:

1. The Court, whose function is to decide in accordance with 

international law such disputes as are submitted to it, shall apply:

a. international conventions, whether general or particular, 

establishing rules expressly recognized by contesting states;

b. international custom, as evidence of a general practice accepted 

as law;

c. the general principles of law recognized by civilized nations;

d. subject to the provisions of Article 59, judicial decisions and the 

teachings of the most highly qualified publicists of the various nations, as 

subsidiary means for the determination of rules of law.

2. This provision shall not prejudice the power of the Court to decide ex 

aequo et bono, if the parties agree thereto.1

Article 38 is a declaration by states that these are the laws under which they 

are willing to be bound. Thus, another statement of sources is the Restatement 

(Third) of Foreign Relations Law of the United States which says:

1. A rule of international law is one that has been accepted as such 

by the international community of states

a) in the form of 

customary law;

b) by international 

agreement; or

'Article 59 says: “The decision of the Court has no binding force except between the parties and in 

respect to that particular case.”

10 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

c) by derivation from general principles common to

the major legal systems of the world.

2. Customary international law results from a general and 

consistent practice of states followed by them from a sense of legal 

obligation.

3. International agreements create law for the states parties thereto 

and may lead to the creation of customary international law which such 

agreements are intended for adherence by states generally and are in fact 

widely accepted.

4. General principles common to the major legal systems, even if 

not incorporated or reflected in customary law or international agreements, 

may be invoked as supplementary rules of international law where 

appropriate.

Briefly, therefore, the “sources” of international law are custom, treaties and 

other international agreements, generally recognized principles of law, judicial 

decisions and teachings of highly qualified and recognized publicists. We shall 

discuss these sources one by one.

Custom or customary law.

Custom or customary international law means “a general and consistent 

practice of states followed by them from a sense of legal obligation.” (Restatement)

This statement contains the two basic elements of custom: the material factor, that 

is, how states behave, and the psychological or subjective factor, that is, why they 

behave the way they do.

The material factor: practice of states or usus

The initial factor for determining the existence of custom is the actual 

behavior of states (usus). This includes several elements: duration, consistency, and 

generality of the practice of states.

The required duration (diuturnitas) can be either short or long. An example 

of customary law that is the result of long, almost immemorial, practice is the rule 

affirmed in The Paquete Havana2

on the exemption of fishing vessels from capture 

as prize of war.

2

175U.S. 677,687 (1900).

CHAPTER 2

THE SOURCES OF INTERNATIONAL LAW

11

We are then brought to the consideration of the question whether, upon the 

facts appearing in these records, the fishing smacks were subject to capture by the 

armed vessels of the United States during the recent war with Spain.

By an ancient usage among civilized nations, beginning centuries ago, and 

gradually ripening into a rule of international law, coast fishing vessels, pursuing 

their vocation of catching and bringing in fresh fish, have been recognized as 

exempt, with their cargoes and crews, from capture as prize of war.

In the North Sea Continental Shelf Cases,3

however, the Court indicated that 

a short duration, by itself, will not exclude the possibility of a practice maturing into 

custom provided that other conditions are satisfied:

. . . Although the passage of only a short period of time is not 

necessarily, or of itself, a bar to the formation of a new rule of 

customary international law on the basis of what was purely a conventional rule, an indispensable requirement would be that within the 

period in question, short though it might be, State practice, including 

that of states whose interests are specially affected, should have been 

both extensive and virtually uniform in the sense of the provision 

invoked — and should moreover have occurred in such a way as to 

show a general recognition that a rule of law or legal obligation is 

involved.

Duration therefore is not the most important element. More important is the 

consistency and the generality of the practice. The basic rule on consistency, that is, 

continuity and repetition, was laid down in the Asylum Case (ICJ Reports 1950). 

The facts in the case were as follows:

On October 3rd, 1948, a military rebellion broke out in Peru; it 

was suppressed the same day. On the following day, a decree was 

published charging a political party, the American People’s 

Revolutionary Party, with having prepared and directed the rebellion. 

The head of the Party, Victor Raul Haya de la Torre, was denounced as 

being responsible. With other members of the party, he was prosecuted 

on a charge of military rebellion....

3

[1%9] ICJ Rep.

12 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

On January 4th, 1949, the Colombian Ambassador in Lima 

informed the Peruvian Government of the asylum granted to Haya de 

la Torre, at the same time he asked that a safe-conduct be issued to 

enable the refugee to leave the country. On January 14th, he further 

stated that the refugee had been qualified as a political refugee. The 

Peruvian Government disputed this qualification and refused to grant a 

safe-conduct. A diplomatic correspondence ensued which terminated 

in the signature, in Lima, on August 31st,

1949, of an Act by which the two Governments agreed to submit the 

case to the International Court of Justice.

The decision of the ICJ was against Colombia:

Finally, as regards American international law, Colombia had 

not proved the existence, either regionally or locally, of a constant and 

uniform practice of unilateral qualification as a right of the State of 

refuge and an obligation upon the territorial State. The facts submitted 

to the Court disclosed too much contradiction and fluctuation to make 

it possible to discern therein a usage peculiar to Latin America and 

accepted as law.

It therefore followed that Colombia, as the State granting 

asylum, was not competent to qualify the nature of the offence by a 

unilateral and definitive decision binding on Peru.

Uniformity and generality of practice need not be complete, but it must be 

substantial. In Nicaragua v. United States (ICJ Reports 1986), the Court said that 

the practice need not be “in absolute conformity” with the purported customary 

rule. It said:

In order to deduce the existence of customary rules, the Court 

deems it sufficient that the conduct of states should, in general, be 

consistent with such rules, and that instances of state conduct 

inconsistent with a given rule should generally have been treated as 

breaches of that rule, not as indications of the recognition of a new 

rule.

Opinio juris

Once the existence of state practice has been established, it becomes 

necessary to determine why states behave the way they do. Do states behave the 

way they do because they consider it obligatory to behave thus or do they do it only 

as a matter of courtesy? Opinio juris, or the belief that a certain form of behavior is 

obligatory, is what makes

CHAPTER 2

THE SOURCES OF INTERNATIONAL LAW

13

practice an international rule. Without it, practice is not law. ... Even humanitarian 

consideration by itself does not constitute opinio juris. As the Nicaragua case again 

put it:

... [f]or a new customary rule to be formed, not only must the 

acts concerned ‘amount to a settled practice,’ but they must be 

accompanied by the opinio juris sive necessitatis. Either the States 

taking such action or other States in a position to react to it, must have 

behaved so that their conduct is “evidence of a belief that this practice 

is rendered obligatory by the existence of a rule of law requiring it.” 

The need for such a belief, i.e., the existence of a subjective element, is 

implicit in the very notion of the opinio juris sive necessitatis.

It should be noted that it is also possible for customary law to develop which 

will bind only several states, or even only two states. But the party claiming it must 

prove that it is also binding on the other party. In the Asylum case, this was not 

proved. But this was proved in the case of Right of Passage over Indian Territory

(ICJ Reports 1960) where the right of Portugal to pass through Indian territory was 

recognized.

Dissenting states; subsequent contrary practice

Would dissenting states be bound by custom? Yes, unless they ha4 

consistently objected to it while the custom was merely in the process of formation. 

The authority that is usually used for this is the Anglo-Norwegian Fisheries* case 

where the ICJ said that a coastline delimitation rule put forward by England “would 

appear to be inapplicable as against Norway, in as much as she has always opposed 

any attempt to apply it to the Norwegian coast.” Dissent, however, protects only the 

dissenter and does not apply to other states. Moreover, a state joining the 

international law system for the first time after a practice has become law is bound 

by such practice.

It is also possible that after a practice has been accepted as law, contrary 

practice might arise. What effect would such contrary practice have? In Fisheries 

Jurisdiction Case (Merits)? the opinion was expressed that such contrary practice 

can cast doubt on the alleged law. It noted “great uncertainty as to the existing 

customary law on account of the conflicting and discordant practice of States.” It

concluded that

4

[1951] 

 

5

[1974] 

 

14 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

the uncertainty had “an unsettling effect on the crystallization of a still evolving 

customary law on the subject.” ... It might be added that, over time, if the contrary 

practice should gain general acceptance, it might instead become the law.

Evidence of state practice and opinio juris

Having said all of the above, what are the acceptable evidence of state 

practice? Various forms of evidence may point to state practice. These can be 

treaties, diplomatic correspondence, statements of national leaders and political 

advisers, as well as the conduct of states. By themselves, however, they do not 

constitute customary law unless characterized by opinio juris.

The existence of opinio juris is a matter of proof. The burden of proving its 

existence falls on the state claiming it. In Nicaragua v. United States where one of 

the issues was whether the prohibition of the use of force was customary law, the 

ICJ said:

It considers that this opinio juris may be deduced from, inter 

alia, the attitude of the Parties and of States towards certain General 

Assembly resolutions, and particularly Resolution 2625 (XXV) 

entitled “Declaration on Principles of International Law concerning 

Friendly Relations and Co-operation among States in Accordance with 

the Charter of the United Nations.” Consent to such resolutions is one 

of the forms of expression of an opinio juris with regard to the 

principle of non-use of force, regarded as a principle of customary 

international law, independently of the provisions, especially those of 

an institutional kind, to which it is subject on the treaty-law plane of 

the Charter.

“Instant custom”

Is there such a thing as “instant custom?” Quite obviously, what is referred to 

as “instant custom” is not the product of constant and prolonged practice. Rather it 

comes about as a spontaneous activity of a great number of states supporting a 

specific line of action. In the after- math of the attack on the Word Trade Center in 

New York, a coalition of forces arose in a matter of months supportive of the action 

taken by the United States against Osama Bin Laden. At least one writer4

has sug

6Antonio Cassese, TERRORISM IS ALSO DISRUPTING SOME CRUCIAL LEGAL CATEGORIES OF INTERNATIONAL LAW, 12 Eur. J. Int’l l, No. 5.

CHAPTER 2

THE SOURCES OF INTERNATIONAL LAW

15

gested that this united action may have given birth to instant customary law 

classifying the attack as an armed attack under Article 51 of the UN Charter 

justifying collective self-defense. What was peculiar about this collective action 

was that the object of defense was not an attack from a state but from a non-state 

organization.

Usus and opinio juris in Humanitarian Law: The Martens Clause

The Martens Clause refers to a paragraph found in the 1899 Hague Peace 

Convention. It says: “Until a more complete code of laws of war has been issued, 

the High Contracting parties deem it expedient to declare that, in cases not included 

in the Regulations adopted by them, the inhabitants and belligerents remain under 

the protection and the rule of the principles of the law of nations as they result from 

the usages established among civilized peoples, from the laws of humanity, and the 

dictates of the public conscience.

This was first inserted by the Russian publicist Fyodor Martens and has 

found its way into a number of treaties including the 1949 Vienna Convention and 

the First Additional Protocol of 1977. It has been cited by, among others, the ICJ in 

the Legality of the Threat or Use of Nuclear Weapons.

What the clause does is to put the “laws of humanity” and the “dictates of 

public conscience” on the same level as “usages of states” or usus thus suggesting 

that even without practice or usus or at least without consistent practice there can 

emerge a principle of law based on laws of humanity and the dictates of public 

conscience. In other words, one need not wait for thousands of civilians to be killed 

before a ban becomes effective.

Treaties.

Another important source are treaties or international agreements, whether 

bilateral or multilateral. Treaties determine the rights and duties of states just as 

individual rights are determined by contracts. Their binding force comes from the 

voluntary decision of sovereign states to obligate themselves to a mode of behavior.

While treaties are generally binding only on the parties, the number of the 

contracting parties and the generality of the acceptance of the rules created by the 

treaty can have the effect of creating a universal law

16 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

in much the same way that general practice suffices to create customary law.

The question is sometimes asked whether treaties are law or are merely 

obligations which the law says must be carried out. On the basis of this question, a 

distinction is made between “contract treaties” or “law making treaties.” The 

distinction, perhaps, is not very useful because all treaties must be observed by the 

parties under the principle of pacta sunt servanda.

Treaties and custom

Whether or not treaties override custom depends on the intention of the 

parties. If the treaty is intended to be declaratory of customary law, it may be seen 

as evidence of customary law.

Normally, treaties and custom can be complementary. As seen, for instance, 

in Nicaragua v. United States, adherence to treaties can be indicative also of 

adherence to practice as opinio juris. What happens, however, when treaty and 

custom contradict each other? Different situations may have different solutions.

If a treaty comes later than a particular custom, as between the parties to the 

treaty, the treaty should prevail. A treaty manifests a deliberate choice of the parties 

and the principle of pacta sunt servanda should be followed. Thus, for instance, in 

the Wimbledon Case (PCIJ 1923), although the PCIJ recognized that customary 

international law prohibited belligerents from ferrying armaments through a neutral 

state, the Court said that Article 380 of the Treaty of Versailles opened the Kiel 

Canal to passage “to the vessels of commerce and of war of all nations at peace 

with Germany on terms of entire equality.”

The Kiel Canal cut through Germany linking the Baltic and North Sea. The 

Court said:

The Court considers that the terms of Article 380 are categorical 

and give rise to no doubt. It follows that the canal has ceased to be an 

internal and national navigable waterway, the use of which by the 

vessels of states other than the riparian state is left entirely to the 

discretion of that state, and that it has become an international 

waterway intended to provide under treaty guarantee easier access to 

the Baltic for the benefit of all nations of the word....

CHAPTER 2

THE SOURCES OF INTERNATIONAL LAW

17

However, if a later treaty is contrary to a customary rule that has the status of 

jus cogens, custom will prevail. This is because of Article 53 of the Vienna 

Convention on the law of Treaties:

A treaty is void if, at the time of its conclusion, it conflicts with 

a peremptory norm of general international law. For the purposes of 

the present Convention, a peremptory norm of general international 

law is a norm accepted and recognized by the international community 

of States as a whole as a norm from which no derogation is permitted 

and which can be modified only by a subsequent norm of general 

international law having the same character.

In a situation, where custom develops after a treaty, the rule is not clear. The 

logical rule perhaps should be that the later custom, being the expression of a later 

will, should prevail. But such an approach would militate against the certainty of 

treaties. In practice, however, an attempt is made to keep the treaty alive by efforts 

at reconciling a treaty with the developing custom. An example given of this 

reconciliation is the Anglo-French Continental Shelf Case (1979). The issue was 

the applicability of the equidistance principle in the delimitation of the continental 

shelves of the United Kingdom and France. The Court said:

Article 6 ... does not formulate the equidistance principle and 

“special circumstances” as two separate rules. The rule there stated in 

each of the two cases is a single one, a combined equidis- tancespecial circumstances rule. ...

The Court does not overlook that under Article 6 the equidistance principle ultimately possesses an obligatory force which it 

does not have in the same measure under the rules of customary law,

for Article 6 makes the application of the equidistance principle a 

matter of treaty obligation for Parties to the Convention. But the 

combined character of the equidistance-special circumstances rule 

means that the obligation to apply the equidistance principle is always 

one qualified by the condition “unless another boundary line is 

justified by special circumstances. ...”

Treaties will be treated in greater detail in Chapter 3.

General principles of law recognized by civilized nations.

The third source cited by the Statute are “the general principles of law 

recognized by civilized nations.” This is also referred to by the

18 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Restatement as “general principles of law recognized by or common to the world’s 

major legal systems.” This has reference not to principles of international law but 

to principles of municipal law common to the legal systems of the world. They 

may, in a sense, be said to belong to no particular system of law but are evidence 

rather of the fundamental unity of law. Most of these principles, however, have 

either become part of customary law or have been incorporated into conventional 

international law.

It is worth noting that the Restatement avoids the language “civilized 

nations.” Its colonial connotation is now unacceptable in the international 

community.

The Restatement refers to them as “supplementary rules of international 

law.” These may be found in “judicial decisions and the teachings of the most 

highly qualified publicists of the various nations” which the Statute refers to as 

“subsidiary means for the determination of rules of law.”

An example would be the 1928 Chorzow Factory case

7 where the 

Permanent Court declared that “it is a general conception of law that every 

violation of an engagement involves an obligation to make reparation.” Another 

example would be the affirmation that private rights acquired under one regime 

does not cease upon the change of government. The principle of estoppel is yet 

another example. Other examples can be given.

The affirmation of general principles of law found in domestic systems as a 

source of international law makes up for the fact that there is no international 

legislative system. The insertion of this provision in Article 38(1) thus plugs some 

of the gaps in the existing international law system. Barcelona Traction Case (ICJ 

1964) adverted to this purpose when it said:

If the Court were to decide the case in disregard of the relevant 

institutions of municipal law, it would without justification, invite 

serious legal difficulties. It would lose touch with reality....

It is to rules generally accepted by municipal systems,... and not to the 

municipal law of a particular State, that international law refers.

CHAPTER 2

THE SOURCES OF INTERNATIONAL LAW

19

More will be said in Chapter 4 on the relation between international law and 

municipal law.

Judicial decisions.

Article 38 of the Statute directs the Court to apply judicial decisions as 

subsidiary means for the determination of the rules of law. But this is made subject 

to Article 59 which says that “the decisions of the court have no binding force 

except between the parties and in respect of that particular case.” Hence, such 

decisions do not constitute stare decisis. However, the decisions of the ICJ are not 

only regarded as highly persuasive in international law circles; they have also 

contributed to the formulation of principles that have become international law. 

Later in this book it will be seen that the ICJ is the source of principles recognizing 

the international personality of international organizations, the doctrine on “genuine 

link” between a person and a state for purposes of jurisdiction, and the straight 

baseline method in drawing baselines for archipelagos. Similarly, arbitral decisions 

have been instrumental on the formation of international law principles.

The teachings of highly qualified writers and “Publicists.”

In many cases of first impression, the only authorities that can be cited are 

writers. The extent to which they are referred to depends on the tradition of the 

court or of individual judges. In common law jurisdictions, there is reluctance to

use them, more so in the US than in Britain. In civil law jurisdictions, there is more 

ready reference to writers. The ICJ is generally reluctant to refer to writers but they 

are often taken into consideration.

“Publicists” are institutions which write on international law. They also play 

a role. The more significant ones are: The International Law Commission, an organ 

of the U.N.; the Institut de Droit International, the International Law Association, a 

multinational body; the (Revised) Restatement of Foreign Relations Law of the 

United States; and the annual publication of the Hague Academy of International 

Law. It should be noted, however, that these institutions are generally government 

sponsored; hence, they bear within themselves a potential for national bias.

20 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Equity.

The Permanent Court of Justice had occasion to use equity as a source of law 

in the case of Diversion of Water from the Meuse (Netherlands v. Belgium).

Netherlands had complained that certain canals constructed by Belgium were in 

violation of an agreement in that the construction would alter the water level and 

rate of flow of the Meuse River. The Court rejected the Netherlands claim and a 

Belgian counterclaim based on the construction of a lock by the Netherlands at an 

earlier time. Judge Hudson, in an individual concurring opinion said:

It would seem to be an important principle of equity that where 

two parties have assumed an identical or a reciprocal obligation, one 

party which is engaged in a continuing non-performance of that 

obligation should not be permitted to take advantage of a similar nonperformance of that obligation by the other party. The principle finds 

expression in the so-called maxims of equity which exercised great 

influence in the creative period of the development of the AngloAmerican law. Some of these maxims are, “Equality is equity”; “He 

who seeks equity must do equity.” It is in line with such maxims that 

“a court of equity refuses relief to a plaintiff whose conduct in regard 

to the subject-matter of the litigation has been improper.” Halsbury’s LAWS 

OF ENGLAND (2nd Ed., 1934), p.

87. A very similar principle was received into Roman Law. The

obligations of a vendor and a vendee being concurrent, “neither could 

compel the other to perform unless he had done, or tendered, his own 

part.”

Judge Hudson justified his use of equity thus:

The Court has not been expressly authorized by its Statute to 

apply equity as distinguished from law. Nor, indeed, does the Statute 

expressly direct its application of international law, though as has been 

said on several occasions the Court is “a tribunal of international law.” 

Series A, No. 7, p. 19; Series A, Nos. 20/21, p.

124. Article 38 of the Statute expressly directs the application of 

“general principles of law recognized by civilized nations,” and in 

more than one nation principles of equity have an established place in 

the legal system. The Court’s recognition of equity as a part of 

international law is in no way restricted by the special power conferred 

upon it “to decide a case ex aequo et bono, if the parties agree 

thereto.” [Citations omitted.] It must be concluded, therefore, that 

under Article 38 of the Statute, if not independently of that Article, the 

Court has some freedom to consider principles of equity as part of the 

international law which it must apply.

CHAPTER 2

THE SOURCES OF INTERNATIONAL LAW

21

Equity, when accepted, is an instrument whereby conventional or customary 

law may be supplemented or modified in order to achieve justice. It has both a 

procedural and substantive aspect. Procedurally, it means a mandate given to a 

judge to exercise discretion in order to achieve a determination that is more

equitable and fair. Different kinds of equity are distinguished: intra legem (within 

the law), that is, the law is adapted to the facts of the case; praeter legem (beyond 

the law), that is, it is used to fill the gaps within the law; and contra legem (against 

the law), that is, a refusal to apply the law which is seen as unjust. Obviously, this 

can be an area of great controversy.

Other supplementary evidence.

UN Resolutions

Declarations of legal principles and Resolutions by the United Nations are 

generally considered merely recommendatory. But if they are supported by all the 

states, they are an expression of opinio juris communis. But a growing number of 

weaker nations, who have a very substantial vote, feel that U.N. Resolutions should 

have the force of law. Resolutions can also be a reflection of what has become 

customary law.

“Soft Law"

Not included among the sources is what a growing literature refers to as “soft 

law.” Others prefer to call this category “non-treaty agreements.” They are 

international agreements not concluded as treaties and therefore not covered by the 

Vienna Convention on the Law of Treaties.

Other sources of soft law are administrative rules which guide the practice of 

states in relation to international organizations. These are mostly administrative 

procedures that are carried out with varying degrees of consistency and uniformity 

that may eventually ripen into customary law or become formalized later on in 

treaties.

Soft law plays an important role in international relations because often 

states prefer non-treaty obligations as a simpler and more flexible foundation for 

their future relations. The difference lies mainly in the wish of the parties to model 

their relationship in a way that excludes the application of treaty or customary law 

on the consequences of a breach of obligations.

Chapter 3 THE LAW OF TREATIES

Treaties can assume various names. They can be conventions, pacts, 

covenants, charters, protocols, concordat, modus vivendi, etc. They represent the 

most deliberate form of commitment through which governments cooperate with 

one another. The generic term that is used is international agreements. In the 

absence of an international legislative body, international agreements are a 

convenient tool through which states are able to project common expectations.

The law on treaties is found in the 1969 Vienna Convention on the Law of 

Treaties. It governs treaties between states. It entered into force in January 1980. 

While the document is not retroactive in effect, it does contain customary law 

precepts antedating 1969.

A Convention on the Law of Treaties Between States and International 

Organizations or Between International Organizations was adopted on March 

26,1986. It should enter into force 30 days after the 35th ratification or accession of 

states.

Definition of treaties.

The Vienna Convention defines a treaty as “an international agreement 

concluded between States in written form and governed by international law, 

whether embodied in a single instrument or in two or more related instruments and 

whatever its particular designation.” The Vienna Convention applies to 

international agreements that satisfy the Convention’s definition, specifically that 

they be in writing and reflective of the intention of the parties to be bound, and 

governed by international law.

While treaties are generally in written form, there are writers who hold that 

even an oral agreement can be binding. However, only writ

22

CHAPTER 3

THE LAW OF TREATIES

23

ten agreements that are new, come under the provisions of the Vienna Convention.

No particular form is prescribed. Thus for instance, in Qatar v. Bahrain,' the 

exchange of notes between the two heads of state was considered an international 

agreement.

QUATAR V. BAHRAIN ICJ 1994

The Parties agree that the exchanges of letters of December 

1987 constitute an international agreement with binding force in their 

mutual relations. Bahrain, however, maintains that the Minutes of 25 

December 1990 were no more than a simple record of negotiations, 

similar in nature to the Minutes of the Tripartite Committee; that 

accordingly they did not rank as an international agreement and could 

not, therefore, serve as a basis for the jurisdiction of the Court.

The Court would observe, in the first place, that international 

agreements may take a number of forms and be given a diversity of 

names. Article 2, paragraph 1 of the Vienna Convention on the Law of 

Treaties of 23 May 1969 provides that for the purposes of that 

Convention, ‘treaty’ means an international agreement concluded 

between States in written form and governed by international law, 

whether embodied in a single instrument or in two or more related 

instruments and whatever its particular designation,” 

Furthermore, as the Court said, in a case concerning a joint

communique, “it knows of no rule of international law which might 

preclude a joint communique from constituting an international 

agreement to submit a dispute to arbitration or judicial settlement” 

(Aegean Sea Continental Shelf; l.CJ. Reports IY78, p. 39, para. 96).

In order to ascertain whether an agreement of that kind has been 

concluded, “the Court must have regard above all to its actual terms 

and to the particular circumstances in which it was drawn up.” (ibid.)

The 1990 Minutes refer to the consultations between the two 

Foreign Ministers of Bahrain and Qatar, in the presence of the For- 

'[1994] ICJ Rep.

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

eign Minister of Saudi Arabia, and state what had been “agreed”

between the Parties. In paragraph 1, the commitments previously 

entered into are reaffirmed (which includes, at the least, the agreement 

constituted by the exchanges of letters of December 1987). In 

paragraph 2, the Minutes provide for the good offices of the King of 

Saudi Arabia to continue until May 1991, and exclude the submission 

of the dispute to the Court prior thereto. The circumstances are 

addressed under which the dispute may subsequently be submitted to 

the Court. Qatar’s acceptance of the Bahraini formula is placed on 

record. The Minutes provide that the Saudi good offices are to 

continue while the case is pending before the Court, and go on to say 

that, if a compromise agreement is reached during that time, the case is 

to be withdrawn.

Thus, the 1990 Minutes include a reaffirmation of obligations 

previously entered into; they entrust King Fahd with the task of 

attempting to find a solution to the dispute during a period of six 

months; and lastly, they address the circumstances under which the 

Court could be seised after May 1991.

Accordingly, and contrary to the contentions of Bahrain, the 

Minutes are not a simple record of a meeting, similar to those drawn 

up within the framework of the Tripartite Committee; they do not 

merely give an account of discussions and summarize points of 

agreement and disagreement. They enumerate the commitments to 

which the Parties have consented. They thus create rights and 

obligations in international law for the Parties. They constitute an 

international agreement.

Bahrain, however, maintains that the signatories of the Minutes 

never intended to conclude an agreement of this kind. It submitted a 

statement made by the Foreign Minister of Bahrain and dated 21 May 

1992, in which the States that “at no time did I consider that in signing 

the Minutes I was committing Bahrain to a legally binding 

agreement.” He goes on to say that, according to the Constitution of 

Bahrain, “treaties ‘concerning the territory of the State’ can come into 

effect only after their positive enactment as a law.” The Minister 

indicates that he would therefore not have been permitted to sign an 

international agreement taking effect at the time of the signature. He 

was aware of that situation, and was prepared to subscribe to a 

statement recording a political understanding, but not to sign a legally 

binding agreement.

The Court does not find it necessary to consider what might 

have been the intentions of the Foreign Minister of Bahrain or,

CHAPTER 3

THE LAW OF TREATIES

25

for that matter, those of the Foreign Minister of Qatar. The two 

Ministers signed a text recording commitments accepted by their 

Governments, some of which were to be given immediate application. 

Having signed such a text, the Foreign Minister of Bahrain is not in a 

position subsequently to say that he intended to subscribe only to a 

“statement recording a political understanding,” and not to an 

international agreement.

The Court concludes that the Minutes of 25 December 1990, 

like the exchanges of letters of December 1987, constitute an international agreement creating rights and obligations for the Parties.

Similar was the case of Norway v. Denmark} The case involved a dispute 

between Denmark and Norway over sovereignty in Eastern Greenland. In the 

course of negotiations, Denmark had offered certain concessions important for 

Norway for the purpose of persuading Norway not to obstruct Danish plans in

regard to Greenland. In reply, the Norwegian Minister accepted the offer: “I told the 

Danish Minister today that the Norwegian Government would not make any 

difficulty in the settlement of this question.” The Court found this declaration sufficient to bind the Norwegian government.

In fact, even a unilateral declaration concerning legal or factual situations 

may create legal obligations. This was what happened in Nuclear Test Cases: 

Australia v. France, New Zealand v. France,

3

France was a signatory to the 

Nuclear Test Ban Treaty and thus continued to conduct tests in the South Pacific 

until 1973. The tests conducted in 1972 and 1973 led to the filing of protests by 

Australia and New Zealand. The case, however, was taken off the Court’s list 

without a decision when France announced by a series of unilateral announcements 

that it would conduct no further tests after 1973. The Court nevertheless 

commented on the legal significance of these announcements saying:

It is well-recognized that declarations made by way of unilateral 

acts concerning legal or factual situations, may have the effect of 

creating legal obligations. Declarations of this kind may be, and often 

are, very specific. When it is the intention of the State making the 

declaration that it should become bound according to

2

[1933] P.C.IJ. Ser. 

3

[ 1974] ICJ Rep.

26 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

its terms, that intention confers on the declaration the character of a 

legal undertaking, the State being thenceforth legally required to 

follow a course of conduct consistent with the declaration. An 

undertaking of this kind, if given publicly, and with an intent to be 

bound, even though not made within the context of international 

negotiations, is binding....

The Court added:

In announcing that the 1974 series of atmospheric tests would 

be the last, the French Government conveyed to the world at large ... 

its intention to terminate these tests. It was bound to assume that other 

States might take note of these statements and rely on their being 

effective. The validity of these statements and their legal consequences 

must be considered within the general framework of the security of 

international intercourse, and the confidence and trust which are so 

essential in the relations among States.

Two characteristics the Court found which convinced it that a binding 

obligation had been incurred. First, the commitment was very specific; second,

there was a clear intent to be bound.

This, however, did not prevent France from conducting nuclear tests in the 

South Pacific. After having conducted six nuclear tests, France responded to 

worldwide outrage and stopped the testing at six in 1996 rather than the originally 

planned eight.

Moreover, care in attributing binding effect to a unilateral declaration was 

expressed in a case involving the Trade Act of 1974 between the European and the 

USA.4

7.118 Attributing international legal significance to unilateral 

statements made by a State should not be done lightly and should be 

subject to strict conditions. Although the legal effects we are ascribing 

to the US statements made to the DSB [Dispute Settlement Body] 

through this Panel are of a more narrow and limited nature and reach 

compared to other internationally relevant instances in which legal 

effect was given to unilateral declarations, we have conditioned even 

these limited effects on the fulfillment

♦CASE CONCERNING SECTIONS 301-310 OF THE TRADE ACT OF 1974 (EUROPEAN UNION 

v. USA, 1999).

CHAPTER 3

THE LAW OF TREATIES

27

of the most stringent criteria. A sovereign State should normally not 

find itself legally affected on the international plane by the casual 

statement of any of the numerous representative speaking on its behalf 

in today’s highly interactive and inter-dependent world nor by a 

representation made in the heat of legal argument on a State’s behalf. 

This, however, is very far from the case before us.

7.121 The statements made by the US before this Panel were a 

reflection of official US policy, intended to express US understanding 

of its international obligations as incorporated in domestic US law. 

The statements did not represent a new US policy or undertaking but 

the bringing of a pre-existing US of a pre-existing US policy and 

undertaking made in a domestic setting into an international forum.

Function of treaties.

Treaties have many functions. They are sources of international law, they 

serve as the charter of international organizations, they are used to transfer territory, 

regulate commercial relations, settle disputes, protect human rights, guarantee 

investments, etc.

The different kinds of treaties may be classified from the standpoint of their 

relevance as source of international law.

The first are multilateral treaties open to all states of the world. They create 

norms which are the basis for a general rule of law. They are either codification 

treaties or “law-making treaties” or they may have the character of both.

Another category includes treaties that create a collaborative mechanism. 

These can be of universal scope {e.g., regulation of allocation of radio frequencies) 

or regional (e.gfishing agreements). They operate through the organs of the 

different states.

The third and largest category of treaties are bilateral treaties. Many of these 

are in the nature of contractual agreements which create shared expectations such as 

trade agreements of various forms. They are sometimes called “contract treaties.”

While treaties are generally binding only on the parties, the number of the 

contracting parties and the generality of the acceptance of specific rules created by 

the treaty can have the effect of creating a

28 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

universal law in much the same way that general practice suffices to create 

customary law.

The making of treaties.

Negotiation Bilateral treaties, and multilateral treaties among a small 

number, generally originate from the foreign ministries. Negotiation is done 

through foreign ministries. Larger multilateral treaties are negotiated in diplomatic 

conferences which are run like a legislative body. Power to negotiate The 

negotiators must possess powers to negotiate. An act relating to the conclusion of a 

treaty by one who has no proper authorization has no legal effect unless confirmed 

by his state:

Article 7. Full powers.

1. A person is considered as representing a State for the 

purpose of adopting or authenticating the text of a treaty or for the 

purpose of expressing the consent of the State to be bound by a treaty 

if:

(a) he produces appropriate full powers; or

(b) it appears from the practice of the States concerned 

or from other circumstances that their intention was to consider 

that person as representing the State for such purposes and to 

dispense with full powers.

2. In virtue of their functions and without having to produce 

full powers, the following are considered as representing their State:

(a) Heads of State, Heads of Government and Ministers for Foreign Affairs, for the purpose of performing all acts 

relating to the conclusion of a treaty;

(b) heads of diplomatic missions, for the purpose of 

adopting the text of a treaty between the accrediting State and 

the State to which they are accredited;

(c) representatives accredited by States to an international conference or to an international organization or one of 

its organs, for the purpose of adopting the text of a treaty in that 

conference, organization or organ.

CHAPTER 3

THE LAW OF TREATIES

29

Authentication of text

Negotiations conclude with the signing of the document. The signatures 

serve as authentication of the document.

Article 9. Adoption of the text:

1. The adoption of the text of a treaty takes place by the 

consent of all the States participating in its drawing up except as 

provided in paragraph 2.

2. The adoption of the text of a treaty at an international 

conference takes place by the vote of two-thirds of the States present 

and voting, unless by the same majority they shall decide to apply a 

different rule.

Article 10. Authentication of the text:

The text of a treaty is established as authentic and definitive:

(a) by such procedure as may be provided for in the text or 

agreed upon by the States participating in its drawing up; or

(b) failing such procedure, by the signature, signature ad 

referendum or initialing by the representatives of those States of the 

text of the treaty or of the Final Act of a conference incorporating the 

text.

The authentication of a treaty makes the text authoritative and 

definitive. It is necessary so that the states will know definitively the 

contents of the text and avoid any misunderstanding as to the terms.

Consent to be bound

Once the document has been signed, there are stages which follow which 

culminate in making the document binding. The most important step is the consent 

to be bound. There are various ways by which consent to be bound is expressed:

Article 11. Means of expressing consent to be bound by a treaty:

The consent of a State to be bound by a treaty may be expressed 

by signature, exchange of instruments constituting a treaty, ratification, 

acceptance, approval or accession, or by any other means if so agreed.

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Article 12. Consent to be bound by a treaty expressed by 

signature:

1. The consent of a State to be bound by a treaty is expressed by the signature of its representative when:

(a) the treaty provides that signature shall have that effect; 

(b) it is otherwise established that the negotiating States were 

agreed that signature should have that effect; or

(c) the intention of the State to give that effect to the signature 

appears from the full powers of its representative or was 

expressed during the negotiation.

2. For the purposes of paragraph 1:

(a) the initialing of a text constitutes a signature of the 

treaty when it is established that the negotiating States so 

agreed; (b) the signature and referendum of a treaty by a 

representative, if confirmed by his State, constitutes a full 

signature of the treaty.

Article 13. Consent to be bound by a treaty expressed by an 

exchange of instruments constituting a treaty:

The consent of States to be bound by a treaty constituted by 

instruments exchanged between them is expressed by that exchange 

when:

(a) the instruments provide that their exchange shall have 

that effect; or (b) it is otherwise established that those States were 

agreed that the exchange of instruments should have that effect, xxx

Article 14. Consent to be bound by a treaty expressed by 

ratification, acceptance or approval:

1. The consent of a State to be bound by a treaty is expressed by ratification when: (a) the treaty provides for such consent to 

be expressed by means of ratification; (b) it is otherwise established 

that the negotiating States were agreed that ratification should be 

required; (c) the representative of the State has signed the treaty 

subject to ratification; or (d) the intention of the State to sign the treaty 

subject to ratification appears from the full powers of its representative 

or was expressed during the negotiation.

2. The consent of a State to be bound by a treaty is expressed by acceptance or approval under conditions similar to those 

which apply to ratification.

CHAPTER 3 31

THE LAW OF TREATIES

The manner of ratification differs from state to state. In the Philippines, it is 

governed by Article VII, Section 21 of the Constitution. But between signature and

ratification a state is required by Article 18(a) not to engage in acts which can 

defeat the purpose of the treaty.

Ratification is next followed by either exchange of ratification, in bilateral 

treaties, or, in multilateral treaties, deposit of ratification:

Article 16. Exchange or deposit of instruments of ratification, 

acceptance, approval or accession:

Unless the treaty otherwise provides, instruments of ratification, 

acceptance, approval or accession establish the consent of a State to be 

bound by a treaty upon:

(a) their exchange between the contracting States; (b) their 

deposit with the depositary; or (c) their notification to the contracting 

States or to the depositary, if so agreed.

Article 17 Consent to be bound by part of a treaty and choice of 

differing provisions:

1. Without prejudice to Articles 19 to 23, the consent of a 

State to be bound by part of a treaty is effective only if the treaty so 

permits or the other contracting States so agree.

2. The consent of a State to be bound by a treaty which 

permits a choice between differing provisions is effective only if it is 

made clear to which of the provisions the consent relates.

Accession to a treaty

States which did not participate in the initial negotiation may also express 

their consent to be bound by “accession.” Article 15 of the Convention says:

The consent of a State to be bound by a treaty is expressed by 

accession when:

(a) the treaty provides that such consent may be expressed by 

that State by means of accession;

(b) it is otherwise established that the negotiating States were 

agreed that such consent may be expressed by that State by means of 

accession; or

(c) all the parties have subsequently agreed that such consent 

may be expressed by that State by means of accession.

32 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Reservations

In deference to the sovereignty of states, the Vienna Convention allows for 

“reservations.” Article 2 defines reservations as “a unilateral statement, however 

phrased or named, made by a State, when signing, ratifying, accepting, approving 

or acceding to a treaty, whereby it purports to exclude or to modify the legal effect 

of certain provisions of the treaty in their application to that State.” In this regard, 

therefore, treaties are different from statutes. Statutes must necessarily apply to all.

Reservations, however, are different from “interpretative declarations” which 

are not meant to be a derogation from the treaty but an expression of how a state 

understands its adoption of the treaty.

The rules on reservations are found in Articles 19 to 23:

Article 19. Formulation of reservations.

A State may, when signing, ratifying, accepting, approving or 

acceding to a treaty, formulate a reservation unless:

(a) the reservation is prohibited by the treaty; (b) the treaty 

provides that only specified reservations, which do not include the 

reservation in question, may be made; or (c) in cases not falling under 

sub-paragraphs (a) and (b), the reservation is incompatible with the 

object and purpose of the treaty.

Article 20. Acceptance of and objection to reservations

1. A reservation expressly authorized by a treaty does not 

require any subsequent acceptance by the other contracting States 

unless the treaty so provides.

2. When it appears from the limited number of the negotiating States and the object and purpose of a treaty that the application of the treaty in its entirety between all the parties is an 

essential condition of the consent of each one to be bound by the 

treaty, a reservation requires acceptance by all the parties.

3. When a treaty is a constituent instrument of an international organization and unless it otherwise provides, a reservation 

requires the acceptance of the competent organ of that organization.

4. In cases not falling under the preceding paragraphs and 

unless the treaty otherwise provides:

(a) acceptance by another contracting State of a reservation constitutes the reserving State a party to the treaty

CHAPTER 3

THE LAW OF TREATIES

in relation to that other State if or when the treaty is in force for 

those States;

(b) an objection by another contracting State to a 

reservation does not preclude the entry into force of the treaty as 

between the objecting and reserving States unless a contrary 

intention is definitely expressed by the objecting State;

(c) an act expressing a State’s consent to be bound by 

the treaty and containing a reservation is effective as soon as at 

least one other contracting State has accepted the reservation.

5. For the purposes of paragraphs 2 and 4 and unless the 

treaty otherwise provides, a reservation is considered to have been 

accepted by a State if it shall have raised no objection to the reservation by the end of a period of twelve months after it was notified of 

the reservation or by the date on which it expressed its consent to be 

bound by the treaty, whichever is later.

Article 21. Legal effects of reservations and of objections to 

reservations:

1. A reservation established with regard to another party in 

accordance with Articles 19,20 and 23:

(a) modifies for the reserving State in its relations with 

that other party the provisions of the treaty to which the 

reservation relates to the extent of the reservation; and

(b) modifies those provisions to the same extent for 

that other party in its relations with the reserving State.

2. The reservation does not modify the provisions of the 

treaty for the other parties to the treaty inter se.

3. When a State objecting to a reservation has not opposed 

the entry into force of the treaty between itself and the reserving State, 

the provisions to which the reservation relates do not apply as between 

the two States to the extent of the reservation.

Article 22. Withdrawal of reservations and of objections to 

reservations:

1. Unless the treaty otherwise provides, a reservation may 

be withdrawn at any time and the consent of a State which has 

accepted the reservation is not required for its withdrawal.

34 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

2. Unless the treaty otherwise provides, an objection to a 

reservation may be withdrawn at any time.

3. Unless the treaty otherwise provides, or it is otherwise 

agreed:

(a) the withdrawal of a reservation becomes operative in 

relation to another contracting State only when notice of it has 

been received by that State; (b) the withdrawal of an objection to 

a reservation becomes operative only when notice of it has been 

received by the State which formulated the reservation.

Article 23. Procedure regarding reservations:

1. A reservation, an express acceptance of a reservation and 

an objection to a reservation must be formulated in writing and 

communicated to the contracting States and other States entitled to 

become parties to the treaty.

2. If formulated when signing the treaty subject to ratification, acceptance or approval, a reservation must be formally 

confirmed by the reserving State when expressing its consent to be 

bound by the treaty. In such a case the reservation shall be considered 

as having been made on the date of its confirmation.

3. An express acceptance of, or an objection to, a reservation made previously to confirmation of the reservation does not 

itself require confirmation.

4. The withdrawal of a reservation or of an objection to a 

reservation must be formulated in writing.

A proliferation of reservations in multilateral treaties can very well defeat the 

purpose of a treaty. In bilateral treaties, a reservation by one party means a rejection 

of the treaty and necessitates re-negotiation. Reservations, therefore, are meant only 

for multilateral treaties.

Must a reservation be consented to by all parties for it to be effective? This 

question was answered by the ICJ in its advisory opinion in Reservations to the 

Genocide Convention (ICJ Reports 1951) saying, by seven votes to five, that “a 

state which has made and maintained a reservation which has been objected to by

one or more parties to the Convention but not by others, can be regarded as a party 

to the Convention if the reservation is compatible with the object and purpose of the 

Convention.” The Court added that compatibility could be decided by

CHAPTER 3

THE LAW OF TREATIES

35

states individually since “if a party to the Convention objects to a reservation which 

it considers incompatible with the object and purpose of the Convention, it can 

consider that the reserving state is not a party to the Convention.” Under this view, it 

is possible for different legal relationships to arise among parties to the same treaty. 

This view some see as reflected in Article 19, supra, of the Vienna Convention.

The Philippines and the 1982 Convention on the Law of the Sea

In this connection, it should be noted that the provision on “archipelagic 

waters” found in the 1982 Convention on the Law of the Sea conflicts with the 

Philippine claim in Article I of the Constitution that the waters connecting the 

islands, irrespective of their breadth and dimension, are “internal waters.” The 

Philippine government is clearly aware of these possible conflicts. Hence, upon its 

ratification of the Convention on the Law of the Sea on August 5,1984, it added the 

following reservation:5

1. The signing of the Convention by the Government of the 

Republic of the Philippines shall not in any manner impair or prejudice the 

sovereign rights of the Republic of the Philippines under and arising from the 

Constitution of the Philippines;

2. Such signing shall not in any manner affect the sovereign rights 

of the Republic of the Philippines as successor to the United States of 

America, under and arising out of the Treaty of Paris between Spain and the 

United States of America of December 10, 1988, and the Treaty of 

Washington between the United States of America and Great Britain of 

January 2,1930;

3.

uch signing shall not diminish or in any manner affect the rights and 

obligations of the Contracting Parties under the Mutual Defense Treaty 

between the Philippines and the United States of America of August 30,1951, 

and its related interpretative instruments; nor those under any pertinent 

bilateral or multilateral treaty or agreement to which the Philippines is a 

party;

5UN Office for Oceans Affairs and the Law of the Sea, Law of the Sea Bulletin, Special Issue 1, March 

1987, Annex II, p. 6, quoted in Sweeney, Oliver, Leech, THE INTERNATIONAL LEGAL SYSTEM 193 (3rd Ed., 1988).

36 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

6. The provisions of the Convention on archipelagic passage 

through sea lanes do not nullify or impair the sovereignty of the Philippines 

as an archipelagic State over the sea lanes and do not deprive it of authority 

to enact legislation to protect its sovereignty, independence, and security;

7. The concept of archipelagic waters is similar to the concept of 

internal waters under the Constitution of the Philippines, and removes straits 

connecting these waters with the economic zone or high sea from the rights 

of foreign vessels to transit passage for international navigation;

The USSR filed a formal protest against the Philippine reservation. However, 

the reservation does not seem to be necessary because Article 8(2) itself says that 

the new rule applies only to “areas which had not previously been considered as” 

internal waters. The 1973 Constitution, which in its Article I classified as internal 

waters what is now referred to as archipelagic waters, pre-dates the 1982 

Convention.

Reservations in Human Rights Treaties

The Human Rights Committee of the UN made the following observations 

regarding reservations in human rights treaties:

17. As indicated above, it is the Vienna Convention on the Law 

of Treaties that provides the definition of reservations and also the 

application of the object and purpose test in the absence of other 

specific provisions. But the Committee believes that its provisions on 

the role of State objections in relation to reservations are inappropriate 

to address the problem of reservations to human rights treaties. Such 

treaties, and the Covenant specifically, are not a web of inter-State 

exchanges of mutual obligations. They concern the endowment of 

individuals with rights. The principle of inter-State reciprocity has no 

place, save perhaps in the limited context of reservations to 

declarations on the Committee’s competence under Article 41. And 

because the operation of the classic rules on reservations is so 

inadequate for the Covenant, States have often not seen any legal 

interest in or need to object to reservations. The absence of protest by 

States cannot imply that a reservation is either compatible or 

incompatible with the object and purpose of the Covenant. Objections 

have been occasional, made by some States but not others, and on 

grounds not always

CHAPTER 3

THE LAW OF TREATIES

37

specified; when an objection is made, it often does not specify a legal 

consequence, or sometimes even indicates that the objecting party 

nonetheless does not regard the Covenant as not in effect as between 

the parties concerned. In short, the pattern is so unclear that it is not 

safe to assume that a non-objecting State thinks that a particular 

reservation is acceptable. In the view of the Committee, because of the 

special characteristics of the Covenant as a human rights treaty, it is 

open to question what effect objections have between States inter se.

However, an objection to a reservation made by States may provide 

some guidance to the Committee in its interpretation as to its 

compatibility with the object and purpose of the Covenant.

Entry into force of treaties

Treaties enter into force on the date agreed upon by the parties. Where no 

date is indicated, the treaty enters into force once consent has been given. 

Multilateral treaties generally contain a provision which says how many states have 

to accept the treaty before it can come into force. The rules on entry into force are 

as follows:

Article 24. Entry into force:

1. A treaty enters into force in such manner and upon such 

date as it may provide or as the negotiating States may agree.

2. Failing any such provision or agreement, a treaty enters into 

force as soon as consent to be bound by the treaty has been established 

for all the negotiating States.

3. When the consent of a State to be bound by a treaty is 

established on a date after the treaty has come into force, the treaty 

enters into force for that State on that date, unless the treaty otherwise 

provides.

4. The provisions of a treaty regulating the authentication of 

its text, the establishment of the consent of States to be bound by the 

treaty, the manner or date of its entry into force, reservations, the 

functions of the depositary and other matters arising necessarily before 

the entry into force of the treaty apply from the time of the adoption of 

its text.

Article 25. Provisional application:

1. A treaty or a part of a treaty is applied provisionally 

pending its entry into force if:

38 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

(a) the treaty itself so provides; or (b) the negotiating 

States have in some other manner so agreed.

2. Unless the treaty otherwise provides or the negotiating 

States have otherwise agreed, the provisional application of a treaty or 

a part of a treaty with respect to a State shall be terminated if that State 

notifies the other States between which the treaty is being applied 

provisionally of its intention not to become a party to the treaty.

Application of treaties

The first fundamental rule on treaties is pacta sunt servanda. Article 26 of 

the Convention says that “every treaty in force is binding upon the parties to it and 

must be performed by them in good faith.”

A second fundamental rule, Article 46, is that a “party may not invoke the 

provisions of its internal law as justification for its failure to perform a treaty.”

As to the territorial scope of its applicability, Article 29 says: “Unless a 

different intention appears from the treaty or is otherwise established, a treaty is 

binding upon each party in respect of its entire territory.”

Interpretation of treaties

Article 31 contains the rules for the interpretation of treaties:

1. A treaty shall be interpreted in good faith in accordance 

with the ordinary meaning to be given to the terms of the treaty in their 

context and in the light of its object and purpose.

2. The context for the purpose of the interpretation of a 

treaty shall comprise, in addition to the text, including its preamble 

and annexes:

(a) any agreement relating to the treaty which was 

made between all the parties in connection with the conclusion 

of the treaty; (b) any instrument which was made by one or 

more parties in connection with the conclusion of the treaty and 

accepted by the other parties as an instrument related to the

treaty.

3. There shall be taken into account, together with the 

context:

CHAPTER 3

THE LAW OF TREATIES

39

(a) any subsequent agreement between the parties 

regarding the interpretation of the treaty or the application of its 

provisions;

b) any subsequent practice in the application of the 

treaty which establishes the agreement of the parties regarding 

its interpretation;

(c) any relevant rules of international law applicable in 

the relations between the parties.

4. A special meaning shall be given to a term if it is established that the parties so intended.

Article 31 combines various approaches to treaty interpretation. Article 31(1) 

follows the “objective” approach, that is, interpretation according to the ordinary 

meaning of the words. This is supplemented by the “teleological” approach in 

Article 31(2), that is, interpretation according to the telos or purpose of the treaty. 

Finally, Article 31(3) and (4) follow a “subjective” approach which honors special 

meaning given by the parties.

Where there are ambiguities in the meaning of a treaty, resort may be made 

to supplementary sources. Articles 32 and 33 are relevant:

Article 32. Supplementary means of interpretation.

Recourse may be had to supplementary means of interpretation, 

including the preparatory work of the treaty and the circumstances of 

its conclusion, in order to confirm the meaning resulting from the 

application of Article 31, or to determine the meaning when the 

interpretation according to Article 31:

(a) leaves the meaning ambiguous or obscure; or

(b) leads to a result which is manifestly absurd or unreasonable.

Article 33. Interpretation of treaties authenticated in two or more 

languages:

1. W

hen a treaty has been authenticated in two or more languages, the text 

is equally authoritative in each language, unless the treaty provides or 

the parties agree that, in case of divergence, a particular text shall 

prevail.

2. A version of the treaty in a language other than one of 

those in which the text was authenticated shall be considered an 

authentic text only if the treaty so provides or the parties so agree.

40 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

3. The terms of the treaty are presumed to have the same 

meaning in each authentic text.

4. Except where a particular text prevails in accordance with 

paragraph 1, when a comparison of the authentic texts discloses a 

difference of meaning which the application of Articles 31 and 32 does 

not remove, the meaning which best reconciles the texts, having regard 

to the object and purpose of the treaty, shall be adopted.

In case there is conflict among “official texts,” the language that is agreed by 

the parties as authoritative is followed.

AIR FRANCE V. SAKS 470 US 392

(Syllabus) Article 17 of the Warsaw Convention makes air 

carriers liable for injuries sustained by a passenger “if the accident 

which caused the damage so sustained took place on board the aircraft 

or in the course of any of the operations of embarking or 

disembarking.” Respondent, while a passenger on petitioner’s jetliner 

as it descended to land in Los Angeles on a trip from Paris, felt severe 

pressure and pain in her left ear, and the pain continued after the 

jetliner landed. Shortly thereafter, respondent consulted a doctor who 

concluded that she had become permanently deaf in her left ear. She 

then filed suit in a California state court, alleging that her hearing loss 

was caused by negligent maintenance and operation of the jetliner’s 

pressurization system. After the case was removed to Federal District 

Court, petitioner moved for summary judgment on the ground that 

respondent could not prove that her injury was caused by an 

“accident” within the meaning of Article 17, the evidence indicating 

that the pressurization system had operated in a normal manner. 

Relying on precedent that defines the term “accident” in Article 17 as 

an “unusual or unexpected” happening, the District Court granted 

summary judgment to petitioner. The Court of Appeals reversed, 

holding that the language, history, and policy of the Warsaw 

Convention and the Montreal Agreement (a private agreement among 

airlines that has been approved by the Federal Government) impose 

absolute liability on airlines for injuries proximately caused by the 

risks inherent in air travel; and that normal cabin pressure changes 

qualify as an “accident” within the definition contained in Annex 13 to 

the Convention on International Civil Aviation as meaning “an 

occurrence associated with the operation of an aircraft.”

CHAPTER 3

THE LAW OF TREATIES

Held: Liability under Article 17 arises only if a passenger’s 

injury is caused by an unexpected or unusual event or happening that is 

external to the passenger, and not where the injury results from the 

passenger’s own internal reaction to the usual, normal, and expected 

operation of the aircraft, in which case it has not been caused by an 

accident under Article 17.

(a) The text of the Warsaw Convention suggests that the 

passenger’s injury must be so caused. The difference in the language 

of Article 17 imposing liability for injuries to passengers caused by an 

“accident” and Article 18 imposing liability for destruction or loss of 

baggage by an “occurrence,” implies that the drafters of the 

Convention understood the word “accident” to mean something 

different than the word “occurrence.” Moreover, Article 17 refers to an 

accident which caused the passenger’s injury, and not to an accident 

which is the passenger’s injury. The text thus implies that, however 

“accident” is defined, it is the cause of the injury that must satisfy the 

definition rather than the occurrence of the injury alone. And, since the 

Warsaw Convention was drafted in French by continental jurists, 

further guidance is furnished by the French legal meaning of 

“accident” — when used to describe a cause of injury, rather than the 

event of injury — as being a fortuitous, unexpected, unusual, or 

unintended event.

(b) The above interpretation of Article 17 is consistent with 

the negotiating history of the Warsaw Convention, the conduct of the 

parties thereto, and the weight of precedent in foreign and American 

courts.

(c) While any standard requiring courts to distinguish causes 

that are “accidents” from causes that are “occurrences” requires 

drawing a line that may be subject to differences as to where it should

fall, an injured passenger is only required to prove that some link in the 

chain of causes was an unusual or unexpected event external to the 

passenger. Enforcement of Article 17’s “accident” requirement cannot 

be circumvented by reference to the Montreal Agreement. That 

Agreement while requiring airlines to waive “due care” defenses under 

Article 20(1) of the Warsaw Convention, did not waive Article 17’s 

“accident” requirement. Nor can enforcement of Article 17 be escaped 

by reference to the equation of “accident” with “occurrence” in Annex 

13, which, with its corresponding Convention, expressly applies to 

aircraft accident investigations and not to principles of liability to 

passengers under the Warsaw Convention.

42 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Invalidity of Treaties.

The usual ground for invalidation of contracts can also invalidate a treaty: 

error of fact, fraud, corruption or duress.

Article 48. Error:

1. A State may invoke an error in a treaty as invalidating its 

consent to be bound by the treaty if the error relates to a fact or 

situation which was assumed by that State to exist at the time when the 

treaty was concluded and formed an essential basis of its consent to be 

bound by the treaty.

2. Paragraph 1 shall not apply if the State in question 

contributed by its own conduct to the error or if the circumstances 

were such as to put that State on notice of a possible error.

3. An error relating only to the wording of the text of a 

treaty does not affect its validity; Article 79 then applies.

Article 49. Fraud:

If a State has been induced to conclude a treaty by the fraudulent conduct of another negotiating State, the State may invoke the 

fraud as invalidating its consent to be bound by the treaty.

Article 50. Corruption of a representative of a State:

If the expression of a State’s consent to be bound by a treaty has 

been procured through the corruption of its representative direcdy or 

indirectly by another negotiating State, the State may invoke such 

corruption as invalidating its consent to be bound by the treaty.

Article 51. Coercion of a representative of a State:

The expression of a State’s consent to be bound by a treaty 

which has been procured by the coercion of its representative through 

acts or threats directed against him shall be without any legal effect.

Article 52. Coercion of a State by the threat or use of force:

A treaty is void if its conclusion has been procured by the threat 

or use of force in violation of the principles of international law 

embodied in the Charter of the United Nations.

Moreover, a violation of jus cogens invalidates a treaty:

Article 53. Treaties conflicting with a peremptory norm of 

general international law (jus cogens):

CHAPTER 3

THE LAW OF TREATIES

43

A treaty is void if, at the time of its conclusion, it conflicts with 

a peremptory norm of general international law. For the purposes of 

the present Convention, a peremptory norm of general international 

law is a norm accepted and recognized by the international community 

of States as a whole as a norm from which no derogation is permitted 

and which can be modified only by a subsequent norm of general 

international law having the same character.

Note, however, that the definition quoted here is based on the legal effect of 

the rule and not on its intrinsic nature. It seems to say that the rule is jus cogens

because no derogation from it is permitted. However, what jus cogens really means 

is that no derogation is allowed because it is jus cogens. It is the intrinsic nature of 

the rule that disallows derogation.

What are the rules considered to be jus cogens ? 

While there is wide acceptance of the existence of jus cogens, there is wide 

dispute as to what principles rank as jus cogens. A 1966 Report of the International 

Law Commission said that there were suggestions to specify what these were. 

Some examples given were: (a) a treaty contemplating an unlawful use of force 

contrary to the provisions of the Charter; (b) a treaty contemplating the performance 

of any other act criminal under international law; (c) a treaty contemplating or conniving towards the commission of acts such as trade in slaves, piracy, or genocide. 

But the Commission decided not to stipulate a list of jus cogens rules for fear of 

being misunderstood and for fear of prolonged debate.

A state, however, can lose the right to assert the invalidity of a treaty. The 

following rules apply:

Article 45. Loss of a right to invoke a ground for invalidating, 

terminating, withdrawing from or suspending the operation of a treaty:

A State may no longer invoke a ground for invalidating, 

terminating, withdrawing from or suspending the operation of a treaty 

under Articles 46 to 50 or Articles 60 and 62 if, after becoming aware 

of the facts:

(a) it shall have expressly agreed that the treaty is valid or 

remains in force or continues in operation, as the case may be; or

44 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

(b) it must by reason of its conduct be considered as having 

acquiesced in the validity of the treaty or in its maintenance in force or 

in operation, as the case may be.

A state, moreover, with limited exception, may not plead its municipal law as a 

ground for invalidating a treaty that has been entered.

Article 46. Provisions of internal law regarding competence to 

conclude treaties:

1. A State may not invoke the fact that its consent to be 

bound by a treaty has been expressed in violation of a provision of its 

internal law regarding competence to conclude treaties as invalidating 

its consent unless that violation was manifest and concerned a rule of 

its internal law of fundamental importance.

2. A violation is manifest if it would be objectively evident 

to any State conducting itself in the matter in accordance with normal 

practice and in good faith.

Article 46. Provisions of internal law regarding competence to 

conclude treaties:

1. A State may not invoke the fact that its consent to be 

bound by a treaty has been expressed in violation of a provision of its 

internal law regarding competence to conclude treaties as invalidating 

its consent unless that violation was manifest and concerned a rule of 

its internal law of fundamental importance.

2. A violation is manifest if it would be objectively evident 

to any State conducting itself in the matter in accordance with normal 

practice and in good faith.

Article 47. Specific restrictions on authority to express the 

consent of a State:

If the authority of a representative to express the consent of a 

State to be bound by a particular treaty has been made subject to a 

specific restriction, his omission to observe that restriction may not be 

invoked as invalidating the consent expressed by him unless the 

restriction was notified to the other negotiating States prior to his 

expressing such consent.

Article 47 is an example of manifest violation.

Amendment and Modification of Treaties.

A distinction is made between amendment and modification of a treaty. 

Amendment is a formal revision done with the participation, at

CHAPTER 3

THE LAW OF TREATIES

45

least in its initial stage, by all the parties to the treaty. Modification, on the other 

hand, involves only some of the parties.

The general rule on amendments, found in Article 39, is that a “treaty may be 

amended by agreement of the parties.” The procedure that is followed is the same 

as that for the formation of treaties.

The process is simple enough with regard to bilateral treaties. In recognition 

of the fact that it is not easy to obtain the consent of all in multilateral treaties, 

Article 40 provides for the possibility of amendments which will affect only some 

states but only after all parties have been given the opportunity to consider the 

proposed amendments. Article 41, for its part, allows for modification of a treaty by 

two or more of the parties.

Amendment

Article 40. Amendment of multilateral treaties:

1. Unless the treaty otherwise provides, the amendment of 

multilateral treaties shall be governed by the following paragraphs.

2. A

ny proposal to amend a multilateral treaty as between all the parties 

must be notified to all the contracting States, each one of which shall 

have the right to take part in:

(a) the decision as to the action to be taken in regard to 

such proposal; (b) the negotiation and conclusion of any 

agreement for the amendment of the treaty.

3. Every State entitled to become a party to the treaty shall 

also be entitled to become a party to the treaty as amended.

4. The amending agreement does not bind any State already 

a party to the treaty which does not become a party to the amending 

agreement; Article 30, paragraph 4(b), applies in relation to such State.

5. Any State which becomes a party to the treaty after the 

entry into force of the amending agreement shall, failing an expression 

of a different intention by that State:

(a) be considered as a party to the treaty as amended; 

and (b) be considered as a party to the unamended treaty in 

relation to any party to the treaty not bound by the amending 

agreement.

46 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Modification

Article 41. Agreements to modify multilateral treaties between 

certain of the parties only — 

1. Two or more of the parties to a multilateral treaty may 

conclude an agreement to modify the treaty as between themselves 

alone if:

(a) the possibility of such a modification is provided 

for by the treaty ; or (b) the modification in question is not 

prohibited by the treaty and:

(i) does not affect the enjoyment by the other 

parties of their rights under the treaty or the performance 

of their obligations; (ii) does not relate to a provision, 

derogation from which is incompatible with the effective 

execution of the object and purpose of the treaty as a 

whole.

2. Unles

s in a case falling under paragraph 1(a) the treaty

otherwise provides, the parties in question shall notify the other

parties of their intention to conclude the agreement and of the 

modification to the treaty for which it provides.

Termination of Treaties.

A treaty may be terminated or suspended according to the terms of the treaty 

or with the consent of the parties. A treaty with a definite period may also expire. It 

may also end when the purpose for the treaty has already been achieved. But a mere 

change of government or severance of diplomatic relations does not terminate or 

suspend a treaty.

Three other important modes of terminating a treaty are material breach, 

impossibility of performance and change of fundamental conditions (rebus sic 

stantibus).

Material breach

Article 60. Termination or suspension of the operation of a 

treaty as a consequence of its breach:

1. A material breach of a bilateral treaty by one of the 

parties entitles the other to invoke the breach as a ground for terminating the treaty or suspending its operation in whole or in part.

2. A material breach of a multilateral treaty by one of the 

parties entitles:

CHAPTER 3

THE LAW OF TREATIES

(a) the other parties by unanimous agreement to 

suspend the operation of the treaty in whole or in part or to 

terminate it either:

(i) in the relations between themselves and

the defaulting State, or

(ii) as between all the parties;

(b) a party specially affected by the breach to invoke it 

as a ground for suspending the operation of the treaty in whole 

or in part in the relations between itself and the defaulting State;

(c) any party other than the defaulting State to invoke 

the breach as a ground for suspending the operation of the treaty 

in whole or in part with respect to itself if the treaty is of such a 

character that a material breach of its provisions by one party 

radically changes the position of every party with respect to the 

further performance of its obligations under the treaty.

3. A material breach of a treaty, for the purposes of this 

article, consists in:

(a) a repudiation of the treaty not sanctioned by the 

present Convention; or

(b) the violation of a provision essential to the 

accomplishment of the object or purpose of the treaty.

4. The foregoing paragraphs are without prejudice to any 

provision in the treaty applicable in the event of a breach.

5. Paragraphs 1 to 3 do not apply to provisions relating to 

the protection of the human person contained in treaties of a 

humanitarian character, in particular to provisions prohibiting any 

form of reprisals against persons protected by such treaties.

Supervening impossibility of performance

Article 61. Supervening impossibility of performance:

1. A party may invoke the impossibility of performing a 

treaty as a ground for terminating or withdrawing from it if the 

impossibility results from the permanent disappearance or destruction 

of an object indispensable for the execution of the treaty. If the 

impossibility is temporary, it may be invoked only as a ground for 

suspending the operation of the treaty.

48 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

2. Impossibility of performance may not be invoked by a 

party as a ground for terminating, withdrawing from or suspending the 

operation of a treaty if the impossibility is the result of a breach by that 

party either of an obligation under the treaty or of any other

international obligation owed to any other party to the treaty.

Rebus sic stantibus

Article 62. Fundamental change of circumstances:

1. A fundamental change of circumstances which has occurred with regard to those existing at the time of the conclusion of a 

treaty, and which was not foreseen by the parties, may not be invoked 

as a ground for terminating or withdrawing from the treaty unless:

(a) the existence of those circumstances constituted an 

essential basis of the consent of the parties to be bound by the 

treaty; and (b) the effect of the change is radically to transform 

the extent of obligations still to be performed under the treaty.

2. A fundamental change of circumstances may not be 

invoked as a ground for terminating or withdrawing from a treaty:

(a) if the treaty establishes a boundary; or (b) if the 

fundamental change is the result of a breach by the party 

invoking it either of an obligation under the treaty or of any 

other international obligation owed to any other party to the 

treaty.

3. If, under the foregoing paragraphs, a party may invoke a 

fundamental change of circumstances as a ground for terminating or 

withdrawing from a treaty it may also invoke the change as a ground 

for suspending the operation of the treaty.

Article 62 is a codification of the common law principle of rebus sic 

stantibus. But the modem approach to it is restrictive. As the ICJ said in the 

Fisheries Jurisdiction case (ICJ Reports 1973),

international law admits that a fundamental change in the

circumstances which determined the parties to accept a treaty, if it has 

resulted in a radical transformation of the extent of the obligations 

imposed by it, may, under certain conditions, afford the party affected 

a ground for invoking the termination or suspension of the treaty.

CHAPTER 3

THE LAW OF TREATIES

49

But the Court also added that the changes “must have increased the burden of 

the obligations to be executed to the extent of rendering performance something 

essentially different from the original intention.”

The following three cases illustrate how difficult it is to establish causes for 

the termination of treaties:

FISHERIES JURISDICTION CASE 

(UNITED KINGDOM V. ICELAND)

ICJ REP 1973 3

[The United Kingdom, as part of what was known as “the 

Cod Wars,” applied to the Court claiming that the proposed 

extension of Iceland’s exclusive fisheries jurisdiction from 12 

miles to SO miles was a breach of an agreement between the 

two states, evidenced by an Exchange of Notes in 1961. Iceland 

contended that the Court had no jurisdiction to hear the case and 

it also submitted that any agreement which it had with the 

United Kingdom not to extend its fisheries jurisdiction, was no 

longer binding due to a fundamental change of circumstances 

since that agreement.

[The court decided that it did have jurisdiction. It also 

considered that Art. 62 of the Vienna Convention on the Law of 

Treaties represented customary international law.]

37. One of the basic requirements embodied [Article 62] is 

that the change of circumstances must have been a fundamental one. In 

this respect the Government of Iceland has, with regard to 

developments in fishing techniques, referred ... to the increased 

exploitation of the fishery resources in the seas surrounding Iceland 

and to the danger of still further exploitation because of an increase in 

the catching capacity of fishing fleets. The Icelandic statements recall 

the exceptional dependence of that country on its fishing for its 

existence and economic development.”

38. The invocation by Iceland of its ‘ vital interests ’, which 

were not made the subject of an express reservation to the acceptance 

of the jurisdictional obligation under the 1961 Exchange of Notes, 

must be interpreted, in the context of the assertion of changed 

circumstances, as an indication by Iceland of the reason why it regards 

as fundamental the changes which in its view have taken place in 

previously existing fishing techniques. This inter- 

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

pretation would correspond to the traditional view that the changes of 

circumstances which must be regarded as fundamental or vital are 

those which imperil the existence or vital development of one of the 

parties.

43. Moreover, in order that a change of circumstances may give 

rise to a ground for invoking the termination of a treaty it is also 

necessary that it should have resulted in a radical transformation of the 

extent of the obligations still to be performed. The change must have 

increased the burden of the obligations to be executed to the extent of 

rendering the performance something essentially different from the 

originally undertaken. In respect of the obligation with which the 

Court is here concerned, this condition is wholly unsatisfied; the 

change of circumstances alleged by Iceland cannot be said to have 

transformed radically the extent of the jurisdictional obligation which 

is imposed in the 1961 Exchange of Notes. The compromissory clause 

enabled either of the parties to submit to the Court any dispute 

between them relating to an extension of Icelandic fisheries 

jurisdiction in the waters above its continental shelf beyond the 12-

mile limit. The present dispute is exactly of the character anticipated in 

the compromissory clause of the Exchange of Notes. Not only has the 

jurisdictional obligation not been radically transformed in its extent; it 

has remained precisely what it was in 1961.

NAMIBIA CASE

ICJ REP 1971 16

[The Security Council had resolved that South Africa’s 

Mandate over South-West Africa (Namibia) was terminated, but 

this had been ignored by South Africa. The Security Council 

then resolved, by Resolution 276 (1970), that the continued 

presence of South Africa in Namibia was illegal. It sought an 

advisory opinion from the Court, asking what were the legal 

consequences for States of the continued presence of South 

Africa in Namibia notwithstanding Resolution 276 (1970). The 

Court held that South Africa was under an obligation to 

withdraw its administration in Namibia. It also held that other 

States where under an obligation not to recognize any acts by 

South Africa’s administration in Namibia (see Chapter 5).]

CHAPTER 3

THE LAW OF TREATIES

94. In examining this action of the General Assembly, it is 

appropriate to have regard to the general principles of international law 

regulating termination of a treaty relationship on account of breach. 

For even if the mandate is viewed as having the character of an 

institution, as is maintained, it depends on those international 

agreements which created the system and regulated its application. As 

the Court indicated in 1962 ‘this Mandate, like practically all other 

similar Mandates’ was a special type of instrument composite in nature 

and instituting a novel international regime. It incorporates a definite 

agreement. (ICJ Rep 1962, p. 331). The Court stated conclusively in 

that Judgment that the Mandate ... ‘in fact and in law, is an 

international agreement having the character of a treaty or convention.’ 

(ICJ Rep 1962, p. 330). The rules laid down by the Vienna Convention 

on the Law of Treaties concerning termination of a treaty relationship 

on account of breach (adopted without a dissenting vote) may in many 

respects be considered as a codification of existing customary law on 

the subject. In the light of these rules, only a material breach of a treaty 

justifies termination, such breach being defined as:

(a) a repudiation of the treaty not sanctioned by the present 

Convention; or

(b) the violation of a provision essential to the accomplishment of the object or purpose of the treaty. (Art. 60, para. 3)

95. General Assembly Resolution 2145 (XXI) determines that 

both forms of material breach had occurred in this case. By stressing 

that South Africa ‘has, in fact, disavowed the Mandate’, the General 

Assembly declared in fact that it had repudiated it. The resolution in 

question is therefore to be viewed as the exercise of the right to 

terminate a relationship in case of a deliberate and persistent violation 

of obligations which destroys the very object and purpose of that 

relationship.

96. It has been contended that the Covenant of the League of 

Nations did not confer on the Council of the League power to 

terminate a mandate for misconduct of the mandatory and that no such 

power could therefore be exercised by the United Nations, since it 

could not derive from the League greater powers than the latter itself 

had. For this objection to prevail it would be necessary to show that the 

mandates system, as established under the League, excluded the 

application of the general principle of law that a right of termination on 

account of breach must be presumed to exist in respect of all treaties, 

except as regards provisions relating

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

to the protection of the human person contained in treaties of a 

humanitarian character (as indicated in Art. 60, para. 5, of the Vienna 

Convention). The silence of a treaty as to the existence of such a right 

cannot be interpreted as implying the exclusion of a right which has its 

source outside the treaty, in general international law, and is dependent 

on the occurrence of circumstances which are not normally envisaged 

when a treaty is concluded.

101. It has been suggested that, even if the Council of the 

League had possessed the power of revocation of the Mandate in an 

extreme case, it could not have been exercised unilaterally but only in 

co-operation with the Mandatory which had committed a serious 

breach of the obligations it had undertaken. To contend, on the basis of 

the principle of unanimity which applied in the League of Nations, that 

in this case revocation could only take place with the concurrence of 

the Mandatory, would not only run contrary to the general principle of 

law governing termination on account of breach, but also postulate an 

impossibility. For obvious reasons, the consent of the wrongdoers to 

such a form of termination cannot be required.

DANUBE DAM CASE 

(Hungary v. Slovakia)

37ILM162 (1998)

[In 1977, Hungary and Czechoslovakia concluded a 

treaty to facilitate the construction of dams on the Danube 

River. Hungary later suspended works due to environmental 

concerns in response to which Czechoslovakia carried out 

unilateral measures. Hungary then claimed the right to terminate 

the treaty, at which point the dispute was submitted to the 

International Court of Justice. Hungary also submitted that it 

was entitled to terminate the Treaty on the ground that 

Czechoslovakia had violated Articles of the Treaty by 

undertaking unilateral measures, culminating in the diversion of 

the Danube. Slovakia became a party to the 1977 Treaty as 

successor to Czechoslovakia (see above on succession).]

100. The 1977 Treaty does not contain any provision 

regarding its termination..

101. The Court will now turn to the first ground advanced by 

Hungary, that of the state of necessity. In this respect, the Court

CHAPTER 3

THE LAW OF TREATIES

will merely observe that, even if a state of necessity is found to exist, it 

is not a ground for the termination of a treaty. It may only be invoked 

to exonerate from its responsibility a State which has failed to 

implement a treaty.

102. Hungary also relied on the principle of the impossibility 

of performance as reflected in Article 61 ... [I]f the joint exploitation of 

the investment was no longer possible, this was originally because 

Hungary did not carry out most of the works for which it was 

responsible; Article 61, paragraph 2, of the Vienna Convention 

expressly provides that impossibility of performance may not be 

invoked for the termination of a treaty by a party to that treaty when it 

results from that party’s own breach of an obligation flowing from that 

treaty.

104. Hungary further argued that it was entitled to invoke a 

number of events which, cumulatively, would have constituted a 

fundamental change of circumstances [changes of political nature, the 

reduced economic viability of the Project, and the progress of 

environmental knowledge and international environmental law]. The 

changed circumstances advanced by Hungary are, in the Court’s view, 

not of such a nature’ that their effect would radically transform the 

extent of the obligations still to be performed in order to accomplish 

the Project. A fundamental change of circumstances must have been 

unforeseen; the existence of the circumstances must have constituted 

an essential basis of the consent of the parties to be bound by the 

treaty.

106. ... [I]t is only a material breach of the treaty itself, by a 

State party to that treaty, which entitles the other party to rely on it as a 

ground for terminating the treaty. The violation of other treaty rules or 

of rules of general international law may justify the taking of certain 

measures, including countermeasures, by the injured State, but it does 

not constitute a ground for termination under the law of treaties.

109. ... Czechoslovakia violated the Treaty only when it 

diverted the waters of the Danube into the bypass canal in October 

1992. In constructing the works which would lead to the putting into 

operation of [the unilateral measure], Czechoslovakia did not act 

unlawfully.

In the Court’s view, therefore, the notification of termination by 

Hungary on 19 May 1992 was premature.

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Procedure for the Termination of Treaties

Article 65. Procedure to be followed with respect to invalidity, 

termination, withdrawal from or suspension of the operation of a treaty 

— 

1. A party which, under the provisions of the present 

Convention, invokes either a defect in its consent to be bound by a 

treaty or a ground for impeaching the validity of a treaty, terminating 

it, withdrawing from it or suspending its operation, must notify the 

other parties of its claim. The notification shall indicate the measure 

proposed to be taken with respect to the treaty and the reasons 

therefor.

2. If, after the expiry of a period which, except in cases of 

special urgency, shall not be less than three months after the receipt of 

the notification, no party has raised any objection, the party making 

the notification may carry out in the manner provided in Article 67 the 

measure which it has proposed.

3. If, however, objection has been raised by any other party, 

the parties shall seek a solution through the means indicated in Article 

33 of the Charter of the United Nations.

4. Nothing in the foregoing paragraphs shall affect the rights 

or obligations of the parties under any provisions in force binding the 

parties with regard to the settlement of disputes.

5. Without prejudice to Article 45, the fact that a State has 

not previously made the notification prescribed in paragraph 1 shall 

not prevent it from making such notification in answer to another party 

claiming performance of the treaty or alleging its violation.

Article 66. Procedures for judicial settlement, arbitration and 

conciliation:

If, under paragraph 3 of Article 65, no solution has been reached 

within a period of 12 months following the date on which the 

objection was raised, the following procedures shall be followed:

(a) any one of the parties to a dispute concerning the 

application or the interpretation of Article 53 or 64 may, by a written 

application, submit it to the International Court of Justice for a 

decision unless the parties by common consent agree to submit the 

dispute to arbitration;

CHAPTER 3

THE LAW OF TREATIES

55

(b) any one of the parties to a dispute concerning the 

application or the interpretation of any of the other articles in Part V of 

the present Convention may set in motion the procedure specified in 

the Annex to the Convention by submitting a request to that effect to 

the Secretary-General of the United Nations.

Article 67. Instruments for declaring invalid, terminating, 

withdrawing from or suspending the operation of a treaty — 

1. The notification provided for under Article 65, paragraph 

1 must be made in writing.

2. Any act declaring invalid, terminating, withdrawing from 

or suspending the operation of a treaty pursuant to the provisions of the 

treaty or of paragraphs 2 or 3 of Article 65 shall be carried out through 

an instrument communicated to the other parties. If the instrument is 

not signed by the Head of State, Head of Government or Minister for 

Foreign Affairs, the representative of the State communicating it may 

be called upon to produce full powers.

Article 68. Revocation of notifications and instruments provided 

for in Articles 65 and 67:

A notification or instrument provided for in Article 65 or 67 may 

be revoked at any time before it takes effect.

Authority to Terminate

While the Vienna Convention enumerates those who have the capacity to 

enter into treaties, it does not say who may terminate a treaty. Logically, however, 

the authority to terminate should also belong to the one who has the authority to 

enter into the treaty. In the Philippines, however, as in the United States, the 

authority to conclude treaties is shared between the Senate and the President. Can 

the President unilaterally terminate a treaty? Goldwater v. Carter,6

discussed this 

question relative to President Carter’s termination of the defense treaty with 

Taiwan. No decision was reached except to say that the matter was not yet ripe for 

judicial review: “The Judicial Branch should not decide issues affecting the 

allocation of power between the President and Congress until the political branches 

reach a constitutional impasse. Otherwise, we would encourage small groups or 

even individual

‘444 U.S. 996 (1979).

56 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Members of Congress to seek judicial resolution of issues before the normal 

political process has the opportunity to resolve the conflict.”

Succession to treaties.

When one state ceases to exist and is succeeded by another on the same 

territory, the question arises whether the new state is bound by the commitments 

made by its predecessor. This subject is taken up by the 1978 Vienna Convention 

on the Succession of States with Respect to Treaties which entered into force on 

November 6,1996.

The Convention follows the “clean slate” rule. Article 16 says: “A newly 

independent State is not bound to maintain in force, or to become a party to, any 

treaty by reason only of the fact that at the date of the succession of States the treaty 

was in force in respect of the territory to which the succession of States relates.” 

But a new state may agree to be bound by the treaties made by its predecessor.

The “clean slate" rule, however, does not apply to treaties affecting boundary 

regimes.

Article 11. Boundary regimes

A succession of States does not as such affect: (a) a boundary 

established by a treaty ; or (b) obligations and rights established by a 

treaty and relating to the regime of a boundary.

Article 12. Other territorial regimes

1. A succession of States does not as such affect: (a) 

obligations relating to the use of any territory, or to restrictions upon 

its use, established by a treaty for the benefit of any territory of a 

foreign State and considered as attaching to the territories in question; 

(b) rights established by a treaty for the benefit of any territory and 

relating to the use, or to restrictions upon the use, of any territory of a 

foreign State and considered as attaching to the territories in question.

2. A succession of States does not as such affect: (a) 

obligations relating to the use of any territory, or to restrictions upon 

its use, established by a treaty for the benefit of a group of States or of 

all States and considered as attaching to that territory;

(b) rights established by a treaty for the benefit of a group of States or 

of all States and relating to the use of any territory, or

CHAPTER 3

THE LAW OF TREATIES

to restrictions upon its use, and considered as attaching to that territory.

3. The provisions of the present article do not apply to treaty 

obligations of the predecessor State providing for the establishment of 

foreign military bases on the territory to which the succession of States

relates.

Chapter 4

INTERNATIONAL LAW AND MUNICIPAL LAW

Dualism vs. Monism.

When a domestic court is confronted with a problem and one of the opposing 

parties relies on municipal law as the proper solution and the other party claims that 

the problem should be solved by international law, what is the court to do? In other 

words, when there is conflict between international law and domestic law, which is 

to prevail?

There are varying theories which try to answer the question. The dualist or 

pluralist theory holds that international law and municipal law are essentially 

different from each other. They differ as to source. Municipal law is a product of

local custom or of legislation whereas the sources of international law are treaties 

and custom grown among states. They differ as regards the relations they regulate. 

Municipal law regulates relations between individual persons under the state 

whereas international law regulates relations between states, They also differ 

regarding their substance. Municipal law is a law of the sovereign over individuals 

whereas international law is a law between sovereign states.

For the dualists, when international law and municipal law conflict, 

municipal law must prevail. The dualists are positivists with a strong emphasis on 

state sovereignty.

Opposite to the dualist theory is the Monistic Theory or Monism. Under this 

theory, international law and domestic law belong to only one system of law. 

However, there are two monist theories. One theory holds that municipal law 

subsumes and is superior to international law, and a second theory, supported by 

Kelsen, holds that international law is superior to domestic law. The superiority of 

international law is seen as flowing from a deep suspicion of local sovereigns and 

from the conviction that international law can imbue the domestic order with a 

sense of moral purpose.

58

CHAPTER 4

INTERNATIONAL LAW AND MUNICIPAL LAW

59

Municipal Law in International Law.

At present the prevailing practice accepts dualism at least in its postulate that 

there are two legal systems. There are prevailing provisions in treaties which 

recognize dualism. Thus, Article 27 of the Vienna Convention on the Law of 

Treaties says, “A party may not invoke the provisions of its internal law as 

justification for its failure to perform a treaty.” Article 13 of the Declaration of 

Rights and Duties of States adopted by the International Law Commission in 1949 

provides: “Every State has the duty to cany out in good faith its obligations arising 

from treaties and other sources of international law, and it may not invoke 

provisions in its constitution or its laws as an excuse for failure to perform this 

duty.” This follows the dualist tradition and blocks domestic law from entry into the 

international arena. Thus, a state which has violated a provision of international law 

cannot justify itself by recourse to its domestic law. Moreover, a state which has 

entered into an international agreement must modify its law to make it conform to 

the agreement. In Exchange of Greek and Turkish Population Case,' the Court 

adverted to “a principle which is self-evident according to which a state which has 

contracted a valid international obligation is bound to make in its legislation such 

modifications as may be necessary to ensure the fulfillment of the obligations 

undertaken.”

But even in dualism, the two systems are not completely separated. Thus, 

Article 38 recognizes the common teachings of domestic law as part of 

international law. Barcelona Traction Case2

said:

If the Court were to decide the case in disregard of the relevant 

institutions of municipal law, it would without justification, invite 

serious legal difficulties. It would lose touch with reality.... It is to 

rules generally accepted by municipal systems,... and not to the 

municipal law of a particular State, that international law refers.

For a situation, moreover, where the court must decide a dispute which turns 

not upon international law but upon domestic law, as in the Brazilian Loans Case3

the Court stated what it must do: “Once the Court has arrived at the conclusion that 

it is necessary to apply the

'Advisory Opinion PCU 

2

[1964] ICJ Rep. 

Trance v. Brazil, PCU 

60 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

municipal law of a particular country, there seems to be no doubt that it must seek 

to apply it as it would be applied in that country....”

International Law in Domestic Law.

Dualism also rules when it comes to entry of international law into the 

domestic sphere. International law, unless it is made part of the domestic system, 

has no role in the settlement of domestic conflicts.

How does international law become part of domestic law for “dualists”? In 

this regard, there are two theories. The first is the doctrine of transformation. This 

is based on a strict dualist approach. Since the two systems are distinct and operate 

separately, for international law to become part of domestic law it must be 

expressly and specifically transformed into domestic law through the appropriate 

constitutional machinery such as an act of Congress or Parliament. This doctrine

flows by analogy from what is applicable to treaties. Treaties do not become part of 

the law of a state unless it is consented to by the state.

The other theory is the doctrine of incorporation. Blackstone expressed this 

in his Commentary when he said that:

the law of nations, wherever any question arises which is properly

the object of its jurisdiction, is here adopted in its full extent by the

common law, and it is held to be part of the law of the land.

What does Philippine law follow? In the case of treaties as international law, 

they become part of the law of the land when concurred in by the Senate in 

accordance with Article VII, Section 21 of the Constitution which sets down the 

mechanism for transforming a treaty into binding municipal law. With regard to 

customary law and treaties which have become customary law, by saying that the 

Philippines “adopts the generally accepted principles of international law as part of 

the law of the land,” the Constitution manifests its adherence to the “dualist” theory 

and at the same time adopts the incorporation theory and thereby makes 

international law part of domestic law. This provision makes the Philippines one of 

the states which make a specific declaration that international law has the force also 

of domestic law.4

International law

4

Similar provisions are found in the Austrian Constitution, Article 9: “The generally recognized rules 

of international law shall be considered as component parts of the Federal Law,” and in Article 25 of the 

Constitution of the Federal Republic of Germany: “The general rules of public international law are an integral 

part of federal law.”

CHAPTER 4 61

INTERNATIONAL LAW AND MUNICIPAL LAW

therefore can be used by Philippine courts to settle domestic disputes in much the 

same way that they would use the Civil Code or the Penal Code and other laws 

passed by Congress.

What elements of international law become part of Philippine law by 

incorporation through Article II, Section 2? Since treaties become apart of 

Philippine law only by ratification, the principle of incorporation applies only to 

customary law and to treaties which have become part of customary law. This 

distinction, however, is sometimes blurred in some Philippine Supreme Court 

decisions.5

There have been occasions when the Supreme Court made use of 

international law to settle domestic problems. In Mejojfv. Director of Prisons,6

an 

alien of Russian descent who had been detained pending execution of the order of 

deportation was ordered released on bail when after two years the deportation order 

could not be carried out because no ship or country would take him. The Court said 

in part:7

Moreover, by its Constitution (Art. II, Sec. 3) the Philippines 

“adopts the generally accepted principles of international law as part of 

the law of the Nation.” And in a resolution entitled “Universal 

Declaration of Human Rights” and approved by the General Assembly 

of the United Nations of which the Philippines is a member, at its 

plenary meeting on December 10, 1948, the right to life and liberty 

and all other fundamental rights as applied to all human beings were 

proclaimed. It was there resolved that “All human beings are bom free 

and equal in degree and rights”

(Art. 1); that “Everyone is entitled to all the rights and freedom set 

forth in this Declaration, without distinction of any kind, such as race, 

color, sex, language, religion, political or other opinion, nationality or 

social origin, property, birth, or other status” (Art.

2)\ that “Everyone has the right to an effective remedy by the 

competent nationals for acts violating the fundamental rights granted 

him by the Constitution or by law” (Art. 8); that “No one shall be 

subjected to arbitrary arrest, detention or exile” (Art. 9); etc.

62 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Earlier, in Kuroda v. Jalandoni,

8

the Court said that the provision “is not 

confined to the recognition of rules and principles of international law as contained 

in treaties to which our government may have been or shall be a signatory.” Thus, 

although the Philippines was not a signatory to the Hague Convention and became 

a signatory to the Geneva Convention only in 1947, the Court held that a Philippine 

Military Commission had jurisdiction over war crimes committed in violation of 

the two conventions prior to 1947. Apparently, the Court considered jurisdiction 

over war crimes part of customary law.

In Agustin v. Edu,9

a case involving a presidential Letter of Instruction 

prescribing the use of early warning devices (EWD), the Court said that the 

constitutional provision “possesses relevance.” The court pointed out that the 1968 

Vienna Convention on Road Signs and Signals had been ratified by the Philippine 

government under Presidential Decree No. 207. “It is not for this country to 

repudiate a commitment to which it had pledged its word. The concept Pacta sunt 

servanda stands in the way of such an attitude, which is, moreover, at war with the 

principle of international morality.”10 Strictly speaking, therefore, the incorporation 

here was done not via the Constitution but by ratification.

Likewise, the international duty of protecting foreign embassies was 

recognized in JBL. Reyes v. Bagatsing." The doctrine of immunity from suit of a 

foreign state is likewise a principle of international law whose acceptance in this 

jurisdiction has been established in a long line of cases starting with Raquiza v. 

Bradford.'2

It was summarized and reaffirmed in Baer v. TizonP

Conflict between International Law and Domestic Law: International Rule

This incorporation or reception of international law into domestic Philippine 

law can become a problem when international law, whether customary or 

conventional, comes into conflict with domestic law, whether constitutional or

statutory. Which law should prevail? It will

INTERNATIONAL LAW AND MUNICIPAL LAW

depend on whether the case goes to a domestic court or to an international tribunal. 

It is an established principle that, before an international tribunal, a state may not 

plead its own law as an excuse for failure to comply with international law. “Every 

State has the duty to carry out in good faith its obligations arising from treaties and 

other sources of international law, and it may not invoke provisions in its 

constitutions or its laws as an excuse for failure to perform this duty.”14 In the advisory opinion on Exchange of Greek and Turkish Populations Case,'5

the Court 

said: “this clause ... merely lays stress on a principle which is self-evident, 

according to which a State which has contracted valid international obligations is 

bound to make in its legislation such modifications as may be necessary to ensure 

the fulfillment of the obligations undertaken.”

This principle of the Vienna Convention has long been established and is 

generally recognized. But an exception is made to the rule by Article 46 of the same 

Convention in cases where the constitutional “violation was manifest and 

concerned a rule of its internal law of fundamental importance.” The same article 

defines the violation as “manifest if it would be objectively evident to any State 

conducting itself in the matter in accordance with normal practice and in good 

faith.” If the treaty that is declared unconstitutional, however, does not come under

the exception, the treaty can be ignored domestically but only at the risk of 

international repercussions before an international court.

Conflict between International Law and Domestic Law: Municipal Rule

The situation, however, is different when the conflict comes before a 

domestic court. Domestic courts are bound to apply the local law. In international

practice, however, courts are very rarely confronted with such a problem. The

reason for this is that courts are generally able to give to domestic law a 

construction which does not conflict with international law. But should conflict 

arise, what rule should be followed and what are the possible consequences?

64 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Conflict may arise between a state’s Constitution and international law. 

Conceivably, however, there should be no such conflict between the Philippine 

Constitution or statutes on the one hand and customary international law on the 

other because the Constitution when formulated accepted the general principles of 

international law as part of the law of the land. Problems can more likely arise 

between treaties on the one hand and the Constitution or statutes on the other.

Should a conflict arise between an international agreement and the 

Constitution, the treaty would not be valid and operative as domestic law. The 

Constitution, in Article VIII, Section 5, 2(a) explicitly recognizes the power of the 

Supreme Court to declare a treaty unconstitutional. This does not mean, however, 

that a treaty that has been declared unconstitutional loses its character as 

international law. Under the “dualist” theory, which the Constitution accepts, the 

unconstitutionality of a treaty is purely a domestic matter. As Article 27 of the 

Vienna Convention on the Law of Treaties says, “A party may not invoke the 

provisions of its internal law as justification for its failure to perform a treaty.”

Of interest here is the manner in which the Supreme Court handled the 

challenge to the Senate’s ratification of the GATT Treaty in Tanada v. Angara}6

The petitioners in the case argued that the “letter, spirit and intent” of the 

Constitution mandating “economic nationalism” were violated by the “parity 

provisions” and “national treatment clauses” scattered in various parts not only of 

the WTO Agreement and its annexes but also in the Ministerial Decisions and 

Declarations and in the Understanding on Commitments in Financial Services. The 

petitioners had relied on the nationalistic provisions of Articles II and XII of the 

Constitution. In reply, the Court said:

By its very title, Article II of the Constitution is a “declaration 

of principles and state policies.” The counterpart of this article in the 

1935 Constitution is called the “basic political creed of the nation” by 

Dean Vicente Sinco. These principles in Article II are not intended to 

be self-executing principles ready for enforcement through the courts. 

They are used by the judiciary as aids or as guides in the exercise of its 

power of judicial review, and by the legislature in its enactment of 

laws. As held in the leading case of

l6G.R. No. 118295, May 2,1997.

CHAPTER 4

INTERNATIONAL LAW AND MUNICIPAL LAW

65

Kilosbayan, Incorporated vs. Morato, the principles and state policies 

enumerated in Article II and some sections of Article XII are not “selfexecuting provisions, the disregard of which can give rise to a cause of 

action in the courts. They do not embody judicially enforceable 

constitutional rights but guidelines for legislation.”

All told, while the Constitution indeed mandates a bias in favor 

of Filipino goods, services, labor and enterprises, at the same time, it 

recognizes the need for business exchange with the rest of the world 

on the bases of equality and reciprocity and limits protection of 

Filipino enterprises only against foreign competition and trade 

practices that are unfair. In other words, the Constitution did not intend 

to pursue an isolationist policy. It did not shut out foreign investments, 

goods and services in the development of the Philippine economy. 

While the Constitution does not encourage the unlimited entry of 

foreign goods, services and investments into the country, it does not 

prohibit them either. In fact, it allows an exchange on the basis of 

equality and reciprocity, frowning only on foreign competition that is 

unfair.

The position of the Court in Tafiada is a retreat from an the earlier case of 

Manila Prince Hotel v. Government Service Insurance System17 where the Court 

said that the command of Article XII, Section 10 was mandatory and selfexecutory. Section 10 says: “In the grant of rights, privileges, and concessions

covering the national economy and patrimony, the State shall give preference to 

qualified Filipinos.” In awarding a contract to a Filipino corporation which had a 

lower bid than that of a Malaysian, the Court said that the command of Section

12 “is a mandatory, positive command which is complete in itself and which needs 

no further guidelines or implementing laws or rules for its enforcement. From its 

very words, the provision does not require any legislation to put it in operation. It is 

per se judicially enforceable.” The Court, however, attempted to justify its new 

position by saying:

It is true that in the recent case of Manila Prince Hotel vs. 

Government Service Insurance System, et al„ this Court held that 

“Sec. 10, second par., Art. XII of the 1987 Constitution is a mandatory, positive command which is complete in itself and which needs 

no further guidelines or implementing laws or rules for its

l7GJt. No. 122156, February 3,1997.

66 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

enforcement. From its very words, the provision does not require any 

legislation to put it in operation. It is per se judicially enforceable.” 

However, as the constitutional provision itself states, it is enforceable 

only in regard to “the grants of rights, privileges and concessions 

covering national economy and patrimony” and not to every aspect of 

trade and commerce. It refers to exceptions rather than the rule. The 

issue here is not whether this paragraph of Sec.

10 of Art. XII is self-executing or not. Rather, the issue is whether, as 

a rule, there are enough balancing provisions in the Constitution to 

allow the Senate to ratify the Philippine concurrence in the WTO 

Agreement. And we hold that there are.

The municipal rule for settling a conflict between international agreement 

and legislation is different. The rule followed in the United States is that treaties 

and statutes are equal in rank and that, since neither is superior to the other, the rule 

followed is that as between an earlier treaty and a later law, the later one prevails. 

As the United States Supreme Court said: “This Court has also repeatedly taken the 

position that an Act of Congress ... is on a full parity with a treaty, and that when a 

statute which is subsequent in time is inconsistent with a treaty, the statute to the 

extent of conflict renders the treaty null.”18 The same rule applies in the Philippines. 

But again, the rule applies only in the domestic sphere. The treaty, even if contrary 

to later statute, remains as international law; while an international tribunal would 

not have the power to reverse the nullification of the treaty in domestic law, it can 

take appropriate action in favor of an aggrieved state.

Illustrative cases

HEAD MONEY CASES EDYE V. ROBERTSON 112 U^. 580 (1884)

A treaty is primarily a compact between independent nations.

It depends for the enforcement of its provisions on the interest and the 

honor of the governments which are parties to it. If these fail, its 

infraction becomes the subject of international negotiations and 

reclamations, so far as the injured party chooses to seek redress, which 

may, in the end, be enforced by actual war. It is obvious that,

18Reid v. Covert, 354 U.S. 1,18 (1957).

CHAPTER 4

INTERNATIONAL LAW AND MUNICIPAL LAW

with all this, the judicial courts have nothing to do, and can give no 

redress.

But a treaty may also contain provisions which confer certain 

rights upon the citizens or subjects of one of the nations residing in the 

territorial limits of the other, which partake of the nature of municipal 

law and which are capable of enforcement as between private parties in 

the courts of the country. An illustration of this character is found in 

treaties which regulate the mutual rights of citizens and subjects of the 

contracting nations in regard to rights of property by descent or 

inheritance when the individuals concerned are aliens. The 

Constitution of the United States places such provisions as these in the 

same category as other laws of Congress by its declaration that this 

Constitution and the laws made in pursuance thereof, and all treaties 

made or which shall be made under authority of the United States, 

shall be the supreme law of the land.

A treaty, then, is a law of the land; it becomes an an act of 

Congress whenever its provisions prescribe a rule by which the rights 

of the private citizen or subject may be determined. And when such 

rights are of a nature to be enforced in a court of justice, that court 

resorts to the treaty for a rule of decision for the case before it as it 

would to a statute.

But, even in this aspect of the case, there is nothing in this law

which makes it irrepealable or unchangeable. The Constitution gives it 

no superiority over an act of Congress in this respect, which may be 

repealed or modified by an act of a later date. Nor is there anything in 

its essential character, or in the branches of the government by which 

the treaty is made, which gives it this superior sanctity.

A treaty is made by the President and the Senate. Statutes are 

made by the President, the Senate, and the House of Representatives. 

The addition of the latter body to the other two in making a law 

certainly does not render it less entitled to respect in the matter of its 

repeal or modification than a treaty made by the other two. If there be 

any difference in this regard, it would seem to be in favor of an act in 

which all three of the bodies participate. And such is, in fact, the case 

in a declaration of war, which must be made by Congress and which, 

when made, usually suspends or destroys existing treaties between the 

nations thus at war.

In short, we are of opinion that, so far as a treaty made by the 

United States with any foreign nation can become the subject

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

of judicial cognizance in the courts of this country, it is subject to such 

acts as Congress may pass for its enforcement, modification, or repeal.

WHITNEY v. ROBERTSON, 124 US. 190 (1888) FIELD, J.

The plaintiffs are merchants, doing business in the city of New 

York; and in August, 1882, they imported a large quantity of 

‘centrifugal and molasses sugars,’ the produce and manufacture of the 

island of San Domingo. These goods were similar in kind to sugars 

produced in the Hawaiian Islands, which are admitted free of duty 

under the treaty with the king of those islands, and the act of congress 

passed to carry the treaty into effect. They were duly entered at the 

custom-house at the port of New York; the plaintiffs claiming that, by 

the treaty with the republic of San Domingo, the goods should be 

admitted on the same terms, that is, free of duty, as similar articles, the 

produce and manufacture of the Hawaiian islands. The defendant, who 

was at the time collector of the port, refused to allow this claim, treated 

the goods as dutiable articles under the acts of Congress....

The plaintiffs appealed from the collector’s decision to the 

secretary of the treasury, by whom the appeal was denied. They then 

paid, under protest, the duties exacted, and brought the present action 

to recover the amount.... The defendant demurred to the complaint, the 

demurrer was sustained, and final judgment was entered in his favor; 

to review which the case is brought here.

... [t]he act of Congress under which the duties were collected, 

authorized their exaction. It is of general application, making no 

exception in favor of goods of any country. It was passed after the 

treaty with the Dominican republic, and, if there be any conflict 

between the stipulations of the treaty and the requirements of the law, 

the latter must control.

A treaty is primarily a contract between two or more independent nations, and is so regarded by writers on public law. For the 

infraction of its provisions a remedy must be sought by the injured 

party through reclamations upon the other. When the stipulations are 

not self-executing, they can only be enforced pursuant to legislation to 

carry them into effect, and such legislation is as much subject to 

modification and repeal by congress as legislation

CHAPTER 4

INTERNATIONAL LAW AND MUNICIPAL LAW

upon any other subject. If the treaty contains stipulations which are 

self-executing, that is, require no legislation to make them operative, to 

that extent they have the force and effect of a legislative enactment. 

Congress may modify such provisions, so far as they bind the United 

States, or supersede them altogether. By the constitution, a treaty is 

placed on the same footing, and made of like obligation, with an act of 

legislation. Both are declared by that instrument to be the supreme law 

of the land, and no superior efficacy is given to either over the other. 

When the two relate to the same subject, the courts will always

endeavor to construe them so as to give effect to both, if that can be 

done without violating the language of either; but, if the two are 

inconsistent, the one last in date will control the other: provided, 

always, the stipulation of the treaty on the subject is self-executing.

If the country with which the treaty is made is dissatisfied with 

the action of the legislative department, it may present its complaint to 

the executive head of the government, and take such other measures as 

it may deem essential for the protection of its interests. The courts can 

afford no redress. Whether the complaining nation has just cause of 

complaint, or our country was justified in its legislation, are not 

matters for judicial cognizance.

In Taylor v. Morton, 2 Curt. 454, 459, this subject was very 

elaborately considered at the circuit by Mr. Justice CURTIS, of this 

court, and he held that whether a treaty with a foreign sovereign had 

been violated by him; whether the consideration of a particular 

stipulation of the treaty had been voluntarily withdrawn by one party,

so that it was no longer obligatory on the other; whether the views and 

acts of a foreign sovereign had given just occasion to the legislative 

department of our government to withhold the execution of a promise 

contained in a treaty, or to act in direct contravention of such promise, 

were not judicial questions; that the power to determine these matters 

had not been confided to the judiciary, which has no suitable means to 

exercise it, but to the executive and legislative departments of our 

government; and that they belong to diplomacy and legislation, and not 

to the administration of the laws. And he justly observed, as a 

necessary consequence of these views, that, if the power to determine 

these matters is vested in congress, it is wholly immaterial to inquire 

whether by the act assailed it has departed from the treaty or not, or 

whether such departure was by accident or design, and, if the latter, 

whether the reasons were good or bad. In these views we fully concur. 

It follows, therefore, that, when a law is

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

clear in its provisions, its validity cannot be assailed before the courts 

for want of conformity to stipulations of a previous treaty not already 

executed. Considerations of that character belong to another 

department of the government. The duty of the courts is to construe 

and give effect to the latest expression of the sovereign will. In HeadMoney Cases, 112 US. 580, 5 Sup. Ct. Rep. 247, it was objected to an 

act of congress that it violated provisions contained in treaties with 

foreign nations, but the court replied that, so far as the provisions of 

the act were in conflict with any treaty, they must prevail in all the 

courts of the country; and, after a full and elaborate consideration of 

the subject, it held that, ‘so far as a treaty made by the United States 

with any foreign nation can be the subject of judicial cognizance in the 

courts of this country, it is subject to such acts as congress may pass 

for its enforcement, modification, or repeal.’

Chapter 5

SUBJECTS OF INTERNATIONAL LAW: STATES

Subjects of International Law.

Subjects of international law are entities endowed with rights and obligations 

in the international order and possessing the capacity to take certain kinds of action 

on the international plane. In other words, they are those who have international 

personality. They are actors in the international legal system and are distinct from 

objects of international law. Objects of international law are those who indirectly 

have rights under or are beneficiaries of international law through subjects of 

international law.

Not all subjects of international law enjoy the same rights and obligations. 

States remain the predominant actors, but other actors have come to be recognized. 

In asserting the international personality of the United Nations, for instance, the 

Reparations Case1

had this to say:

The subjects of law in any legal system are not necessarily 

identical in their nature or in the extent of their rights, and their nature 

depends upon the needs of the community. Throughout its history, the 

development of international law has been influenced by the 

requirements of international life, and the progressive increase in the 

collective activities of States has already given rise to instances of 

action upon the international plane by certain entities which are not 

States....

States enjoy the fullest personality in international law. They will be the 

concern of this chapter. Other subjects will be treated in the following chapter.

'[1949] ICJ Rep.

71

72 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

States: Commencement of their Existence.

There are various situations when the question of statehood arises. Examples 

are when a portion of a territory has seceded, or when there is foreign control over 

the affairs of an entity which claims to be a state, or when states have formed a 

union but continue to retain some autonomy, and when individual members of a 

federation claim statehood.

The traditional statement of the characteristics which make an entity a state 

is found in the Montevideo Convention of 1933 on Rights and Duties of States:

“The state as a person of international law should possess the following 

qualifications: (a) a permanent population; (b) a defined territory; (c) government; 

(d) the capacity to enter into relations with other States.” Hence, the definition of 

the concept “state” which has found currency among Philippine writers is this: it is 

a community of persons more or less numerous, permanently occupying a definite 

portion of territory, independent of external control, and possessing an organized 

government to which the great body of inhabitants render habitual obedience. 

Commentators, following the Montevideo Convention, break down the concept 

into four elements: people, territory, government, and sovereignty

People or Population

As an element of a state, “people” simply means a community of persons 

sufficient in number and capable of maintaining the permanent existence of the 

community and held together by a common bond of law. It is of no legal 

consequence if they possess diverse racial, cultural, or economic interests. Nor is a 

minimum population required.

Territory

A definite territory over which an entity exercises permanent sovereignty is 

another element of a state. But as the Restatement (Third) on the Foreign Relations 

Law of the United States explains: “An entity may satisfy the territorial 

requirement for statehood even if its boundaries have not been finally settled, if one 

or more of its boundaries are disputed, or if some of its territory is claimed by

another state. An entity does not necessarily cease to be a state even if all its 

territory has been occupied by a foreign power or if it has otherwise lost control of 

its territory temporarily.”2

2

§ 201. U.S. courts generally view the Restatement as an authoritative scholarly statement of 

contemporary international law.

CHAPTER 5

SUBJECTS OF INTERNATIONAL LAW: STATES

73

Government

Government, as an element of a state, is defined as “that institution or 

aggregate of institutions by which an independent society makes and carries out 

those rules of action which are necessary to enable men to live in a social state, or 

which are imposed upon the people forming that society by those who possess the 

power or authority of prescribing them.”3

International law does not specify what 

form a government should have. Moreover, for purposes of international law, it is 

the national government that has legal personality and it is the national government 

that is internationally responsible for the actions of other agencies and 

instrumentalities of the state. Finally, a temporary absence of government, for 

instance during an occupation by a foreign power, does not terminate the existence 

of a state.

Sovereignty

Sovereignty means independence from outside control. The Montevideo 

Convention expresses this in positive terms as including “the capacity to enter into 

relations with other States.” This latter element of sovereignty, however, is 

dependent on recognition.

An entity may in fact possess all the elements of a state but if one or more 

states do not extend recognition to it, the entity would not be able to establish 

relations with those states. Incidentally, although the Philippines was not yet an 

independent state in 1945, it was accepted as one of the original signatories of the 

United Nations Charter.

Self-determination

Sovereignty as an element of a state is related to but not identical with the

broader concept of the right of self-determination. In the post- World War II era, 

there have arisen numerous new states. The impetus behind the birth of new states 

is the principle of self-determination of peoples. Both the International Covenant 

on Civil and Political Rights and the International Covenant on Economic, Social, 

and Cultural Rights assert the principle of self determination of people in identical 

language: “All peoples have the right of self-determination. By virtue of that right 

they freely determine their political status and freely pursue

3U.S. v. Dorr, 2 Phil. 332, cited in Bacani v. NACOCO, 100 Phil. 468,471 (1956).

74 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

their economic, social and cultural development.” This principle has been affirmed 

and reaffirmed by various documents of the United Nations, notably the 

Declaration on the Granting of Independence to Colonial Countries and Peoples 

(1960) and the Declaration on Principles of International Law concerning Friendly 

Relations and Cooperation among States in accordance with the Charter of the 

United Nations. (1970).

The various levels of claim to self-determination may be broken down into 

two main categories. The first is the establishment of new states — that is, the 

claim by a group within an established state to break away and form a new entity. 

The second does not involve the establishment of a new state. This can simply be 

claims to be free from external coercion, or the claim to overthrow effective rulers 

and establish a new government, that is, the assertion of the right of revolution; or 

the claim of people within an entity to be given autonomy.

The UN has used various means to give effect to self-determination: 

resolutions of support for demands, sanctions for offenses against selfdetermination, helping in ascertaining the will of the people, giving rights of 

participation in international fora, inquiries and reports, military force to maintain 

order, formulation of criteria whether self- government exists, and technical 

assistance. But international law has not recognized a right of secession from a 

legitimately existing state.

Recognition of states.

When State A recognizes State B, it means that both recognize the capacity 

of each other to exercise all the rights belonging to statehood. Recognition thus 

means the act of acknowledging the capacity of an entity to exercise rights 

belonging to statehood.

Can an entity claim to be a state before it is recognized by other states? 

There are two views on this. One view, the declaratory theory, is that recognition 

is merely “declaratory” of the existence of the state and that its being a state 

depends upon its possession of the required elements and not upon recognition. A 

recognizing state merely accepts an already existing situation. The weight of 

authority favors the “declaratory view.”

The other view, the constitutive theory, is that recognition “constitutes” a 

state, that is, it is what makes a state a state and confers legal

CHAPTER 5

SUBJECTS OF INTERNATIONAL LAW: STATES

75

personality on the entity. In effect, this merely emphasizes the point that states are 

under no obligation to enter into bilateral relations. But then states may decide to 

recognize an entity as a state even if it does not have all the elements of a state 

found in the Montevideo Convention.

In an extended article on recent practice of states relative to recognition, the 

author draws the following conclusion:4

The main conclusion to be drawn is that the question of recognition of states has become less predictable and more a matter of 

political discretion as a result of recent practice. The traditional criteria 

for statehood retain an uneasy existence alongside the new EC 

Guidelines, which have been particularly influential in relation to the 

recognition of the new states emerging from the USSR and 

Yugoslavia.

The anarchic situation in Georgia led some countries to refrain 

from recognizing that country in accordance with the traditional 

criteria while in the case of the Republic of Bosnia and Herzegovina 

the international community used recognition in an attempt to arrest 

what looked like an inevitable slide into anarchy.

Issues such as the presence of foreign forces on a country’s soil 

have been treated inconsistently or glossed over. This is 

understandable because there are times when train timetables cannot 

keep up with the march of history. A valid distinction could be made 

between situations which are the remnants of the Cold War such as the 

continuing presence of former Soviet troops in Germany and situations 

of hostile occupation such as the hold of Belgrade-supported local 

Serbian forces over large slabs of Croatia and Bosnia and 

Herzegovina. Yet even in the latter case, the absence of control by the 

central government over large parts of its territory did not halt 

recognition. Nor has the continuing unwelcome presence of ‘Soviet’ 

forces in the Baltic republics detracted from their independence in 

international eyes.

At the same time, the absence of foreign forces from the former 

Yugoslav Republic of Macedonia (which was accomplished when the 

Yugoslav People’s Army completed its withdrawal from Macedonia in 

March 1992) has not led states to accept that territory as a fit subject of 

recognition.

4Roland Rich, RECOGNITION OF STATES: THE COLLAPSE OF YUGOSLAVIA AND THE SOVIET UNION, 4 Eur. J Int’l L, No. 1 (1993).

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Membership of the UN has also been seen differently by 

different countries insofar as a vote in favour may amount to 

recognition. India decided to extend recognition before Croatia, 

Slovenia and Bosnia and Herzegovina joined the UN. Sweden took the 

view that, having participated in the unanimous decision of the UN 

General Assembly to accept the membership of Bosnia and 

Herzegovina, ‘this according to Swedish practice means that Sweden 

has recognized the Republic of Bosnia and Herzegovina.’ The 

Swedish view has considerable merit in that membership of the UN is 

only open to states and voting in favour of a new member state’s 

application would seem to imply a statement of recognition of that 

new state. However, other states take a different view. Both Chile and 

Sri Lanka for example, having participated in the UN General 

Assembly vote admitting the Republic of Bosnia and Herzegovina, 

nevertheless considered it necessary a few days later to extend 

recognition on a bilateral basis.

It now seems that the ‘political realities’ have gained primacy 

over the inclinations to maintain consistency by applying accepted 

criteria to test the fact of statehood. This should not be seen as 

necessarily a negative development. The application of the traditional

criteria as the test for statehood and therefore the rationale behind 

recognition was largely amoral. How a government came to be in 

effective control over its territory was, for the most part, not 

considered to be a relevant factor. The adoption of conditions leading 

to recognition is an attempt to introduce a greater moral dimension. 

Yet the enemy of such a moral stand is inconsistency, the very factor 

which the traditional criteria tried to avoid. And there can be fewer 

better examples of inconsistency than the continuing refusal to 

recognize the independence of the former Yugoslav Republic of 

Macedonia even though it meets every criterion and every condition 

but simply refuses to change its name. The ‘political realities’ in this 

case seem to have more to do with internal EC politics than with the 

merits of the Macedonian case.

The EC’s 12 December 1992 Edinburgh summit dealt with the 

question of the former Yugoslav Republic of Macedonia but did not 

advance the matter significantly. While falling short of endorsing the 

line taken at the Lisbon summit in relation to recognition, the 

Edinburgh summit did not really review this position and simply left 

EC Foreign Ministers seized of the question. Authorities in Skopje 

may have no alternative but to

CHAPTER 5

SUBJECTS OF INTERNATIONAL LAW: STATES

77

consider the EC position as an abdication of the leadership role 

hitherto played by the EC. This could lead the government in Skopje to 

the conclusion that it should seek UN membership thus by-passing the 

EC altogether. In such circumstances, the issue of the effect of a vote 

for membership of the UN on the question of recognition will need to 

be closely considered by UN members.

Reverting to the long-running debate about whether recognition 

is declaratory or constitutive, recent events seem to point towards a 

trend to attempt to constitute states through the process of recognition. 

Bosnia and Herzegovina is an obvious example but Ukraine can also 

be seen to fit into this category.

The end of the Cold War will lead to many new situations where 

peoples will not feel as constrained as in the past to attempt to exercise 

their right to self-determination. In response to this phenomenon the 

international community is now faced with a far more complex 

problem than in the recent past. Old ideas about equating the status quo 

to stability, about the unacceptability of secession, about considering 

peoples only in terms of the states they live in and about the 

inviolability of existing international frontiers will be re-examined. 

When considering a question of recognition, states will have to ask

themselves questions about whether such an action will contribute to a 

peaceful resolution of a conflict, and if the answer is in the affirmative, 

the traditional criteria for statehood may well have to be finessed.

Nor should we expect this new situation to be limited to the 

problems of Europe. The principles involved are universal and the new 

issues to be confronted may soon be seen to be problems on a global 

scale.

Recognition of Government.

Closely related to recognition of states is recognition of governments. It 

means the act of acknowledging the capacity of an entity to exercise powers of 

government of a state.

If a change in government in an existing state comes about through ordinary 

constitutional procedure, recognition by others comes as a matter of course. The 

problem is acute when a new government within a state comes into existence 

through extra-constitutional means. The following are two cases involving 

recognition of government:

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

THE TINOCO ARBITRATION

Great Britain v. Costa Rica (1923)

William H. Taft, Arbitrator

In January 1917, the Government of Costa Rica, under President 

Alfredo Gonzalez, was overthrown by Federico Tenneco. Tenneco’s 

government concluded certain contracts with British Corporations. 

Tenneco retired and left the country. After Tenneco’s retirement the 

old constitution was restored and a Law of Nullities was passed 

annulling the contracts concluded during the Tenneco regime. Great 

Britain made claims on the basis of the injuries done to its nationals 

caused by the annulments. There were two preliminary questions: 1. 

What was the status of the Tinoco regime in international law. 2. Was 

Great Britain estopped from pursuing its claims because it never 

recognized the Tinoco government either de jure or de facto.

Taft ...

But it is urged that many leading Powers refused to 

recognize the Tinoco government. ... Undoubtedly, recognition 

by other Powers is an important evidential factor in establishing 

proof of the existence of a government in the society of nations.

The non-recognition by other nations of a government 

claiming to be a national personality, is usually appropriate 

evidence that it has not attained the independence and control 

entitling it by international law to be classed as such. But when 

recognition of a government is by such nations determined by 

inquiry, not into its de facto sovereignty and complete 

governmental control, but into its illegitimacy or irregularity of 

origin, their non-recognition loses something of evidential 

weight... [it] cannot outweigh the evidence disclosed by this 

record before me as to the de facto character of Tinoco’s 

government....

Second. It is ... argued on behalf of Costa Rica that the 

Tinoco government cannot be considered a de facto 

government, because it was not established and maintained in 

accord with the constitution of Costa Rica of 1871. To hold that 

a government... does not become a de facto government unless 

it conforms to a previous constitution would be to hold that 

within the rules of international law a revolution contrary to the 

fundamental law of the existing government

CHAPTER 5

SUBJECTS OF INTERNATIONAL LAW: STATES

cannot establish a new government. This cannot be, and is 

not,true....

Third. It is further objected by Costa Rica that Great Britain by 

her failure to recognize the Tinoco government is estopped now to 

urge claims of her subjects dependent upon the acts and

contracts of the Tinoco government Here the executive of Great

Britain takes the position that the Tinoco government which it did not 

recognize, was nevertheless a de facto government that could create

rights in British subjects which it now seeks to protect. Nonrecognition may have aided the succeeding government to come into 

power; but subsequent presentation of claims based on the de facto

existence of the previous government ... does not work an injury to the 

succeeding government in the nature of a fraud or breach of good 

faith.

UPRIGHT v. MERCURY BUSINESS MACHINES CO.

Supreme Court of New York, Appellate Division,

First Department, 1961.

13 A.D.2d 36,213 N.Y.S.2d 417

BREITEL, JUSTICE PRESIDING. Plaintiff, an individual, sues 

as the assignee of a trade acceptance drawn on and accepted by

defendant in payment for business typewriters sold and delivered to it 

by a foreign corporation. The trade acceptance is in the amount of $27 

307.45 and was assigned to plaintiff after dishonor by defendant.

Involved on this appeal is only the legal sufficiency of the first 

affirmative defense. It alleges that the foreign corporation is the 

creature of the East German Government, a government not 

recognized by the United States. It alleges, moreover, that such 

corporation is an enterprise controlled by and that it is an arm and 

instrument of such government.

On motion addressed to its sufficiency Special Term sustained 

the defense. For the reasons that follow the defense should have been 

stricken as legally insufficient....

A foreign government, although not recognized by the 

political arm of the United States Government, may nevertheless 

have de facto existence which is juridically cognizable. The acts 

of such a de facto government may affect private rights and 

obligations arising either as a result of activity in, or with 

persons or corporations within, the

territory controlled by such de facto government. This is 

traditional law. (Russian Reinsurance Co. v. Stoddard, 240 N.Y. 

149, 147 N.E. 703; M. Salimoff & Co. v. Standard Oil Co., 262 

N.Y. 220,186 N.E. 679, 89 ALJi. 345)

Consequences of Recognition or Non-recognition.

In a world of growing interdependence, recognition or nonrecognition of 

government can have very serious consequences. A government, once recognized, 

gains increased prestige and stability. The doors of funding agencies are opened, 

loans are facilitated, access to foreign courts and immunity from suit are gained. 

Military and financial assistance also come within reach. The absence of formal 

recognition, on the other hand, bars an entity from all these benefits or, at least, 

access to them may be suspended. 

Recognition of a government, however, like recognition of a state involves a 

highly political judgment. The United States, for instance, refused for many years 

to recognize the government of the People’s Republic of China or of North Korea

not because it was not obvious that these governments had effective control of their 

territory but because the United States did not wish these governments to benefit 

from the legal effects of recognition.

Does admission of a government to the United Nations mean recognition by 

all members? No. The recognition is only to the extent of the activities of the 

organization.

While recognition of a state is not the same as recognition of government, 

the two often go together in the case of new states. However, within established 

states, governments come and go with no effect on recognition of the state. It 

should be noted, moreover, that recognition of government does not mean approval 

of the recognized government’s methods. Nor do diplomatic relations connote 

approval; they are intended merely to secure a convenience.

An illustration of the political nature of recognition may be found in United 

States history. In the 19th century, Daniel Webster said that nations have the 

discretion to govern themselves and to choose which agency to represent them. In 

1792, after the French Revolution, Jefferson said that the US would deal with any

government effectively in power.

CHAPTER 5

SUBJECTS OF INTERNATIONAL LAW: STATES

81

In subsequent years, however, the US required more than just effective 

control by the incoming government. Woodrow Wilson said that the US should not 

deal with governments set up in violation of their constitution. After the 

Communists took over in China in 1949, Truman said that the US would not deal 

with a government imposed by a foreign power. When Chinese troops entered the 

Korean war, Dulles said that the policy of the United States was to recognize de 

facto governments when (1) they control government, (2) are not confronted with

active resistance in the country, and (3) are willing to live up to international

obligations.

When is recognition terminated? The answer is fairly simple: recognition of 

a regime is terminated when another regime is recognized. For as long as a state 

continues to meet the qualifications of statehood, its status as a state cannot be 

“derecognized.” When the United States recognized the government of China in 

1979, it derecognized the government of Taiwan, but continued with commercial, 

cultural, and other non-governmental relationships.

Succession of States.

Succession or Continuity

States do not last forever. The issue of state succession can arise in different 

circumstances. Existing sovereignties can disappear under different circumstances. 

New political sovereigns may arise as the result of decolonization, dismemberment 

of an existing state, secession, annexation and merger. In each of these cases an 

existing sovereignty disappears either in whole or in part and a new one arises thus 

giving rise to questions of succession to rights and obligations.

The international law and practice of states on this subject have been 

confused. Some on one extreme suggest that the new state succeeds to no rights or 

obligations of the predecessor state but begins with a tabula rasa. Others on 

another extreme hold that the successor state assumes all the obligations and enjoys 

all the rights of the predecessor. Others hold that succession has varying effects on 

state rights and duties.

The issue of continuity is also particularly problematic. When a new state 

arises, what is its relation to the predecessor state? Is it completely distinct from the 

predecessor state or is it a continuation of the

82 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

predecessor state? There are cases when there are no problems. For instance, the 

present India is a continuation of the former British India while Pakistan is a 

completely new state. But there are also very problematic situations. Take for 

instance the Soviet Union and the Yugoslavia.

After the USSR was dissolved, Russia claimed to be a continuation of the 

USSR and therefore entitled to membership not only in the UN but also in the 

Security Council. Russia’s claim was supported by the Decision of the Council of 

Heads of State of the Commonwealth of the Independent States on December 21, 

1991. But the Baltic states of Estonia, Latvia and Lithuania, which had been 

annexed by the Soviet Union in 1940, declared their independence. The European 

Community adopted a resolution welcoming the restoration of the sovereignty of 

the Baltic states in 1991. So did the United States.

The problem of Yugoslavia, however, is more complicated. The mother state

was the Socialist Federal Republic of Yugoslavia. Over a period of several months, 

this state collapsed and the component republics declared independence. Majorities 

in Bosnia and Herzegovina voted for independence in a referendum and this was 

recognized by the Arbitration Commission of Yugoslavia. The European 

Community recognized Slovenia, Croatia and Bosnia and these were admitted to 

the United Nations. Serbia and Montenegro, however, formed a new state called the 

Federal Republic of Yugoslavia and maintained that they were the continuation of 

the former mother state. This claim was opposed by the other republics and by the 

international community. In 1992, the Security Council even declared that “the state 

formerly known as the Socialist Federal Republic of Yugoslavia has ceased to 

exist.”

In November 2000, Yugoslavia applied for membership in the UN thereby 

abandoning its claim to continuity of SFRY.

Succession of States

The issues on succession can be succession to territory, to treaties, to 

property and contracts. The rules may be summarized thus:5

When a state succeeds another state with respect to particular territory,

the capacities, rights and duties of the predecessor

’The summary given here is taken from THIRD RESTATEMENT OF FOREIGN RELATIONS LAW. 

CHAPTER 5

SUBJECTS OF INTERNATIONAL LAW: STATES

state with respect to that territory terminate and are assumed by the 

successor state.

As to state property, subject to agreement between predecessor 

and successor states, title passes as follows:

(a) where part of the territory of a state becomes territory of 

another state, property of the predecessor state located in that territory 

passes to the successor state;

(b) where a state is absorbed by another state, property of the 

absorbed state, wherever located, passes to the absorbing state;

(c) where part of a state becomes a separate state, property of 

the predecessor state located in the territory of the new state passes to 

the new state.

With respect to public debts, subject again to agreement 

between the states concerned, responsibility for the public debt of the 

predecessor, and rights and obligations under its contracts, remain with 

the predecessor state, except as follows:

(a) where part of the territory of a state becomes territory of 

another state, local public debt, and the rights and obligations of the 

predecessor state under contracts relating to that territory, are 

transferred to the successor state;

(b) where a state is absorbed by another state, the public debt, 

and rights and obligations under contracts of the absorbed state, past to 

the absorbing state;

(c) where part of a state becomes a separate state, local public 

debt, and rights and obligations of the predecessor state under contracts 

relating to the territory of the new state, pass to the new state.

With respect to treaties (already touched on in the Chapter on 

Treaties), the Vienna Convention is followed. The rules are:

(1) When part of the territory of a state becomes territory of 

another state, the international agreements of the predecessor state 

cease to have effect in respect of the territory and the international 

agreements of the successor state come into force there. This reflects 

the “moving treaty rule” or “moving boundaries rule.” If X has a treaty 

with Y, and part of Y is transferred to Z, X may seek relief from treaty 

obligation under “rebus sic stantibus.’’

(2) When a state is absorbed by another state, the international agreements of the absorbed state are terminated and the

84 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

international agreements of the absorbing state become applicable to 

the territory of the absorbed state. Third states may appeal to rebus sic 

stantibus.

(3) When a part of a state becomes a new state, the new state 

does not succeed to the international agreements to which the 

predecessor state was party, unless, expressly or by implication, it 

accepts such agreements and the other party or parties thereto agree or 

acquiesce. This applies the “clean slate theory.”

(4) Pre-existing boundary and other territorial agreements 

continue to be binding notwithstanding. This is the uti possidetis rule.

The consequences of the re-unification of West and East Germany were 

governed by the German Unification Treaty of 1990. The special case of 

Hongkong’s return to China in 1997 were governed by the 1984 Sino-British Joint 

Declaration on the Question of Hongkong.

Fundamental Rights of States.

Independence

Independence is the capacity of a state to provide for its own well-being and 

development free from the domination of other states, providing it does not impair

or violate their legitimate rights. As a right, independence means the right to

exercise within its portion of the globe, to the exclusion of others, the functions of a 

state.6 But restrictions upon a state’s liberty arising either from customary law or 

from treaties do not deprive a state of independence.

Flowing from independence are certain other rights such as jurisdiction over 

its territory and permanent population, the right to self defense and the right of 

legation. Independence also involves the duty not to interfere in the internal affairs 

of other states.

Equality

Equality obviously does not mean equality in political or economic power. 

Rather, it means equality of legal rights irrespective of the size or power of the 

state. Within the General Assembly, the doctrine

6

Island of Las Palmas Arbitration [ 1928].

CHAPTER 5

SUBJECTS OF INTERNATIONAL LAW: STATES

85

means one state, one vote. The UN Charter, Article 2, provides that “the 

Organization is based on the principle of the sovereign equality of all its 

Members.” Hence, each has one vote in the General Assembly and every state may 

aspire for the offices in the various organs of the UN.

Peaceful co-existence

This right has been developing over the past twenty years. The theory was 

elaborated in 1954 as the Five Principles of Co-existence by India and China and 

includes mutual respect for each other’s territorial integrity and sovereignty, mutual 

non-aggression, non interference in each other’s affairs and the principle of 

equality. This has also been expressed in other documents such as the 1970 

Declaration on Principles of International Law Friendly Relations and Cooperation 

Among States.

Some Incomplete Subjects.

Protectorates. Protectorates are largely of historical importance. They are 

dependent states which have control over their internal affairs but whose external 

affairs are controlled by another state. They were sometimes referred to as 

autonomous states, vassal states, semisovereign or dependent states

Federal state. This is a union of previously autonomous entities. Various 

arrangements are possible. One arrangement may involve placing full authority in a 

central organ while another arrangement might lodge authority in the individual 

entities to the detriment of the central organ. The central organ will have personality 

in international law; but the extent of international personality of the component 

entities can be a problem.

Mandated and Trust Territories. Mandated territories were territories placed 

by the League of Nations under one or other of the victorious allies of World War I. 

The mandate system was replaced by the trusteeship system after World War II 

under the Trusteeship Council. For instance, the Carolines, Marianas and Marshall 

Islands were placed under the trusteeship of the United States. These have been in 

the process of evolution and self-determination since 1986.

Taiwan. Taiwan seems to be a non-state territory which de jure is part of 

China. But it is too affluent and strategically located to be over

86 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

looked by international actors. It is interesting that when Taiwan sought accession 

to the GATT treaty it did not do so as a state but as part of a “customs territory.”

The Sovereign Order of Malta. There was a time when the order had 

sovereignty over Malta. This has since been lost. But the Italian Court of Cassation 

in 1935 recognized its international personality. Currently, it has diplomatic 

relations with over forty states.

The Holy See and Vatican City. In 1929, the Lateran Treaty was signed with 

Italy which recognized the state of the Vatican City and “the sovereignty of the 

Holy See in the field of international relations as an attribute that pertains to the 

very nature of the Holy See, in conformity with its traditions and the demands of its 

mission in the world.” It has no permanent population.

Chapter 6

OTHER SUBJECTS OF INTERNATIONAL LAW

States are the dominant subjects of international law. But there are others: 

international organizations, insurgents, liberation movements, and, in a more 

limited way, individuals.

1. International Organizations.

Establishment, international personality, immunity

In the matter of international organizations, there are three general questions 

that need to be discussed. First, how do they come into existence? Second, do they 

have international personality? Third, do they enjoy any kind of immunity?

An international organization is an organization that is set up by treaty 

among two or more states. It is different from non-governmental organizations 

(NGO) which are set up by private persons. The constituent document of 

international organizations therefore is a treaty. For this reason, only states are 

members of international organizations. As the ICJ put it in its Advisory Opinion 

on the Use of Nuclear Weapons (1996) about the World Health Organization:

The Court observes that in order to delineate the field of activity 

or the area of competence of an international organization, one must 

refer to the relevant rules of the organization and, in the first place, to 

its constitution. From a formal standpoint, the constituent instruments 

of international organizations are multilateral treaties, to which the 

well-established rules of treaty interpretation apply.

But they are also treaties of a particular type; their object is to create 

new subjects of law endowed with a certain autonomy, to which the 

parties entrust the task of realizing common goals.

Such treaties can raise specific problems of interpretation owing, inter 

alia, to their character which is conventional and at the same

87

88 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

time institutional; the very nature of the organization created, the 

objectives which have been assigned to it by its founders, the 

imperatives associated with the effective performance of its functions, 

as well as its own practice, are all elements which may deserve special 

attention when the time comes to interpret these constituent treaties.

That international organizations have international personality was 

established in the oft-quoted Reparations Case (ICJ Advisory Opinion, 1949) 

involving the international personality of the United Nations. The question raised 

was formulated thus:

“I. In the event of an agent of the United Nations in the 

performance of his duties suffering injury in circumstances involving 

the responsibility of a State, has the United Nations, as an 

Organization, the capacity to bring an international claim against the 

responsible de jure or de facto government with a view to obtaining 

the reparation due in respect of the damage caused

(a) to the United Nations, (b) to the victim or to persons entitled 

through him?

The Court answered the question after rephrasing it:

Do the provisions of the Charter relating to the functions of the 

Organization imply that the latter is empowered to assure its agents 

limited protection? These powers, which are essential to the 

performance of the functions of the Organization, must be regarded as 

a necessary implication arising from the Charter. In discharging its 

functions, the Organization may find it necessary to entrust its agents 

with important missions to be performed in disturbed parts of the 

world. These agents must be ensured of effective protection. It is only

in this way that the agent will be able to carry out his duties 

satisfactorily. The Court therefore reaches the conclusion that the 

Organization has the capacity to exercise functional protection in 

respect of its agents. The situation is comparatively simple in the case 

of Member States, for these have assumed various obligations towards 

the Organization.

But what is the situation when a claim is brought against a State 

which is not a Member of the Organization? The Court is of opinion 

that the Members of the United Nations created an entity possessing 

objective international personality and not merely personality 

recognized by them alone. As in the case of Question 1(a), the Court 

therefore answers Question 1(b) in the affirmative.

CHAPTER 6

OTHER SUBJECTS OF INTERNATIONAL LAW

89

The Court had to answer the question because the UN Charter is silent about 

the organization’s international personality. In the case of other organizations, the 

charter itself might specifically endow it with international personality. But if it 

does not, possession of international personality may be implied from the functions 

of the organization, as in the case of the UN.

Although international organizations have personality in international law, 

their powers and privileges are by no means like those of states. Their powers and 

privileges are limited by the constituent instrument that created them. To quote 

again from the Advisory Opinion on the Use of Nuclear Weapons cited supra:

The Court goes on to point out that international organizations 

are subjects of international law which do not, unlike States, possess a 

general competence. International organizations are governed by the 

“principle of speciality," that is to say, they are invested by the States 

which create them with powers, the limits of which are a function of 

the common interests whose promotion those States entrust to them.

The powers conferred on international organizations are 

normally the subject of an express statement in their constituent 

instruments. Nevertheless, the necessities of international life may 

point to the need for organizations, in order to achieve their objectives, 

to possess subsidiary powers which are not expressly provided for in 

the basic instruments which govern their activities.

It is generally accepted that international organizations can exercise 

such powers, known as “implied” powers.

Immunities

Because they enjoy international personality, they can also be given the 

immunities and privileges of international persons. Their immunities, however, 

have for basis not sovereignty, as it is for states, but the need for the effective 

exercise of their functions.

In the case of the United Nations, the immunities are spelled out in Article 

105 of the UN Charter:

1. The Organization shall enjoy in the territory of each of its

Members such privileges and immunities as are necessary for the fulfillment 

of its purposes.

90 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

2. Representatives of the Members of the United Nations and 

officials of the Organization shall similarly enjoy such privileges and 

immunities as are necessary for the independent exercise of their functions in 

connection with the Organization.

3. The General Assembly may make recommendations with a 

view to determining the details of the application of paragraphs 1 and 2 of 

this Article or may propose conventions to the Members of the United 

Nations for this purpose.

This has been supplemented by the General Convention on the Privileges 

and Immunities of the United Nations (1946) and by the Convention and Privileges 

of Specialized Agencies (1947).

There is no common law doctrine recognizing the immunity of international 

organizations. Their immunities come from the conventional instrument creating 

them a clear example of the grant of immunity is the 1946 General Convention on 

the Privileges and Immunities of the United Nations.

The Philippine Court has affirmed the immunity of other international 

organization in International Catholic Migration Commission v. Calleja,1

Southeast Asian Fisheries Development Center v. Acosta, and Lasco v. United 

Nations Revolving Fund for Natural Resources Exploration?

A curious case, however, is the case of Kapisanan ng mga Manggagawa v. 

The International Rice Research Institute (IRRI) decided jointly with the 

International Catholic Migration case. IRRI was created not by a treaty but by a 

Memorandum of Agreement between the Philippine Government on the one hand 

and the Rockefeller and Ford Foundations, two private organizations. It is therefore 

not an international organization. Initially, IRRI was organized and registered with 

the Securities and Exchange Commission as a private corporation subject to all 

laws and regulations. However, by virtue of Pres. Decree No. 1620, promulgated on 

19 April 1979, IRRI was granted the status, prerogatives, privileges and immunities 

of an international organization. The Supreme Court has consistently recognized 

the immunity granted

'G.R. No. 85750, September 28,1990.

’G.R. Nos. 109095-109107, February 

23,1995. 

CHAPTER 6

OTHER SUBJECTS OF INTERNATIONAL LAW

91

to IRRI declaring it to be on the same footing as the International Catholic 

Migration Commission.

The Court recognized that the Catholic Migration Commission was a 

“specialized agency” under the Charter of the United Nations. Likewise, without 

giving the reason why, it recognized the IRRI as an international organization. The 

Court said:

The grant of immunity from local jurisdiction to ICMC and 

IRRI is clearly necessitated by their international character and 

respective purposes. The objective is to avoid the danger of partiality 

and interference by the host country in their internal workings.

The exercise of jurisdiction by the Department of Labor in these 

instances would defeat the very purpose of immunity, which is to 

shield the affairs of international organizations, in accordance with 

international practice, from political pressure or control by the host 

country to the prejudice a member States of the organization, and to 

ensure the unhampered performance of their functions.

The end result of the protective blanket that has been wrapped around IRRI is 

the efforts of employees to seek redress for violations of labor rights have been 

repeatedly rebuffed by the Supreme Court. For all practical purposes, they are 

denied the protection given by the Constitution in Article XIII, Section 3 

guaranteeing full protection for labor.

There have also been two cases involving the immunity of the Asian 

Development Bank (ADB). The bank’s Charter is a treaty to which the Philippines 

is a party. The first case was Department of Foreign Affairs v. National Labor 

Relations Board,3 where the issue was whether the National Labor Relations 

Commission could assume jurisdiction over a case of illegal dismissal against 

ADB. In upholding the immunity of the ADB, the Court appealed to the provisions 

of the ADB’s Charter:

Article 50(1) of the Charter provides:

The Bank shall enjoy immunity from every form of legal 

process, except in cases arising out of or in connection with the 

exercise of its powers to borrow money, to guarantee obligations, or to 

buy and sell or underwrite the sale of securities.

’G.R.No. 113191, September 18,1996.

92 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Similar provisions are found in the Headquarters Agreement. Thus, its 

Section 5 reads:

The Bank shall enjoy inununity from every form of legal 

process, except in cases arising out of, or in connection with, the 

exercise of its powers to borrow money, to guarantee obligations, or to 

buy and sell or underwrite the sale of securities.

The Court concluded:

The above stipulations of both the Charter and Headquarters 

Agreement should be able, nay well enough, to establish that, except in 

the specified cases of borrowing and guarantee operations, as well as 

the purchase, sale and underwriting of securities, the ADB enjoys 

immunity from legal process of every form....

The Court reiterated what it had said in World Health Organization v. 

Aquino.*

It is a recognized principle of international law and under our 

system of separation of powers that diplomatic immunity is essentially 

a political question and courts should refuse to look beyond a 

determination by the executive branch of the government, and where 

the plea of diplomatic immunity is recognized and affirmed by the 

executive branch of the government.... it is then the duty of the courts 

to accept the claim of immunity upon appropriate suggestion by the 

principal law officer of the government, ... or other officer acting under 

this direction. Hence, in adherence to the settled principle that courts 

may not so exercise their jurisdiction ... as to embarrass the executive 

arm of the government in conducting foreign relations, it is accepted 

doctrine that ‘in such cases the judicial department of government 

follows the action of the political branch and will not embarrass the 

latter by assuming an antagonistic jurisdiction.

The World Health case was an original action for certiorari and prohibition 

to set aside respondent judge’s refusal to quash a search warrant issued by him at 

the instance of Constabulary officers for the search and seizure of the personal 

effects of an official of the World Health Organization.

4G.R. No. L-35131, November 29,1972.

CHAPTER 6

OTHER SUBJECTS OF INTERNATIONAL LAW

93

The second case was Jeffrey Liang (Hue Feng) v. People .

5

The case 

involved a criminal complaint against Jeffrey Liang, an ADB official, for grave oral 

defamation. Appeal was made to the political character of Jeffrey Liang as an agent 

of international organization. But the Court ruled that the immunity granted to 

officers and staff of the ADB was not absolute; but limited to acts performed in an 

official capacity and could not cover the commission of a crime such as slander or

oral defamation in the name of official duty.

The United Nations: Structure and Powers

The principal international organization is the United Nations. It came into 

being on October 24,1945, when the UN Charter came into force. The membership 

now includes almost all the world’s independent nations. Admission to membership 

is governed by Article 4 which says:

The UN is a universal organization charged with peacekeeping 

responsibilities, the development of friendly relations among nations, 

the achievement of international cooperation in solving international 

problems of an economic, social, cultural and humanitarian character, 

and the promotion of human rights and fundamental freedoms for all 

human beings without discrimination. Article 1 of the Charter says that 

the UN can include “all other peace-loving states which accept the 

obligations contained in the present Charter and, in the judgment of the 

Organization, are able and will to carry out these obligations.” As new 

independent nations arise, the number of members continue to grow.

The Purposes of the United Nations are:

1. To maintain international peace and security, and to that 

end: to take effective collective measures for the prevention and 

removal of threats to the peace, and for the suppression of acts of 

aggression or other breaches of the peace, and to bring about by 

peaceful means, and in conformity with the principles of justice and 

international law, adjustment or settlement of international disputes or 

situations which might lead to a breach of the peace;

2. To develop friendly relations among nations based on 

respect for the principle of equal rights and self-determination

5G.R. No. 125865, March 26,2001.

94 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

of peoples, and to take other appropriate measures to strengthen 

universal peace;

3. To achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian 

character, and in promoting and encouraging respect for human rights 

and for fundamental freedoms for all without distinction as to race, 

sex, language, or religion; and

4. To be a center for harmonizing the actions of nations in 

the attainment of these common ends.

The UN, however, is enjoined against intervening in matters which are 

“essentially within the domestic jurisdiction” of any state. Article 2(7) says:

Nothing contained in the present Charter shall authorize the 

United Nations to intervene in matters which are essentially within the 

domestic jurisdiction of any state or shall require the Members to 

submit such matters to settlement under the present Charter; but this 

principle shall not prejudice the application of enforcement measures 

under Chapter VII.

In the hierarchy of international organizations, the UN occupies a position of 

preeminence. Article 103 says that “in the event of a conflict between the 

obligations of the Members of the United Nations under the present Charter and 

their obligations under any other international agreement, their obligations under 

the present Charter shall prevail.” This clause is known as the “international 

constitutional supremacy clause.”

The principal organs of the UN are the General Assembly, the Security 

Council, the Economic and Social Council (ECOSOC), the Trusteeship Council, 

the International Court of Justice (ICJ), and the Secretariat.

General Assembly

In the General Assembly, all members are represented. It has plenary powers 

in the sense that it “may discuss any question or any matters within the scope of the 

... Charter.” (Article 10)

The GA distinguishes between “important questions” and “other questions.” 

Important questions are decided by a two-thirds majority of the members voting 

and present. “Other questions” require only a

CHAPTER 6

OTHER SUBJECTS OF INTERNATIONAL LAW

95

majority. The Charter identifies what the “important questions” are and the GA 

may, by a majority vote, identify other important questions. (Article 18[3])

Security Council

The Security Council has “primary responsibility for the maintenance of 

international peace and security.” (Article 24[1]) There are 15 member states, five 

of them permanent (China, France, Russia [in place of the former USSR], United 

Kingdom and the US). The others are elected for two year terms in accordance with 

equitable geographic representation.

The Security Council distinguishes between “procedural matters” and “all 

other matters.” Matters that are not procedural require nine affirmative votes, 

including the “concurring votes of the permanent members.” (Article 27[3]) But 

since the Charter does not specify what matters are procedural, the Council practice 

is that a decision on whether a matter is procedural or not also requires the 

concurrence of the permanent members. Hence, a double veto by the permanent 

members is possible. And an abstention is considered a veto.

ECOSOC

The ECOSOC has 54 member states elected for three year terms. It has a 

large number of subsidiary organs, among them the UN Commission on Human 

Rights and the Commission on the Status of Women.

Trusteeship Council

The Trusteeship Council supervises non-self governing territories. Its 

jurisdiction has already become very limited. Palau was the last entity to be under 

the Council. The Council suspended operations after Palau became independent on 

1 October 1994.

Secretariat

The Secretariat “shall comprise a Secretary General and such staff as the 

Organization may require.” (Article 97) The Secretary General is elected to a five 

year term by the General Assembly upon the recommendation of the Security 

Council, subject to veto power. He is the chief administrator of the organization and 

has the power to “bring to the attention of the Security Council any matter which in 

his opinion

96 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

may threaten the maintenance of international peace and security.” (Article 99)

International Court of Justice

The International Court of Justice is the principal judicial organ of the UN. 

This will be treated in another chapter.

Other Agencies

Aside from the main organs of the UN, there are also specialized agencies. 

Some of these are: the United Nations Educational, Scientific and Cultural 

Organization (UNESCO). The International Civil Aviation Organization (ICAO), 

the World Health Organization (WHO), the Food and Agricultural Organization 

(FAO), the World Bank and the International Monetary Fund (IMF).

Regional Organizations: ASEAN

Regional organizations also play an important role. But they are neither 

organs nor subsidiary organs of the UN. They are autonomous international 

organizations having an institutional affiliation with the UN by concluding 

agreements with the UN. (Article 5). They are international institutions created by 

international agreements for the purpose of dealing with regional problems in 

general or with specific matters be they economic, military or political.

The regional organization of South East Asian nations is the ASEAN. It was 

established on 8 August 1967 in Bangkok, Thailand, with the signing of the 

Bangkok Declaration by the five original Member Countries namely Indonesia, 

Malaysia, Philippines, Singapore and Thailand.

Brunei Darussalam joined the Association on 8 January 1984. Vietnam 

became the seventh member of ASEAN on 28 July 1995. Laos and Myanmar were 

admitted into ASEAN on 23 July 1997. Cambodia also became a member in 1999.

The Bangkok Declaration united the ASEAN Member Countries in a joint 

effort to promote economic cooperation and the welfare of the people in the region. 

The Bangkok Declaration set out guidelines for ASEAN’s activities and defined the 

aims of the organization.

The ASEAN nations came together with three main objectives in mind: to 

promote the economic, social and cultural development of the region through 

cooperative programs; to safeguard the political and economic stability of the 

region against big power rivalry; and to serve as a forum for the resolution of intraregional differences.

The ASEAN Declaration states that the aims and purposes of the Association 

are: (1) to accelerate economic growth, social progress and cultured development in 

the region and (2) to promote regional peace and stability through abiding respect 

for justice and the rule of law in the relationship among countries in the region and 

adherence to the principles of the United Nations Charter.

The ASEAN Vision 2020, adopted by the ASEAN Leaders on the 30th 

Anniversary of ASEAN, agreed on a shared vision of ASEAN as a concert of 

Southeast Asian nations, outward looking, living in peace, stability and prosperity, 

bonded together in partnership in dynamic development and in a community of 

caring societies.

In 2003, the ASEAN Leaders resolved that an ASEAN Community shall be 

established comprising three pillars, namely, ASEAN Security Community, 

ASEAN Economic Community and ASEAN Socio- Cultural Community.

ASEAN Member Countries have adopted the following fundamental 

principles in their relations with one another, as contained in the Treaty of Amity 

and Cooperation in Southeast Asia (TAC):

— mutual respect for the independence, sovereignty, equality, territorial 

integrity, and national identity of all nations;

— the right of every State to lead its national existence free from 

external interference, subversion or coercion;

— non-interference in the internal affairs of one another;

— settlement of differences or disputes by peaceful manner;

— renunciation of the threat or use of force; and

— effective cooperation among themselves.

All ten members have already ratified the Charter and it will take effect upon 

the deposit of all ratifications.

98 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

2. Insurgents.

Protocol II

The first and only international agreement exclusively regulating the conduct 

of parties in a non-international armed conflict is the 1977 Protocol II to the 1949 

Geneva Conventions. It “develops and supplements Article 3, infra, common to the 

Geneva Conventions of 12 August 1949 without modifying its existing conditions 

or application.” A non-international armed conflict covered by this expanded 

guarantee is defined in Article I. They are armed conflicts

which take place in the territory of a High Contracting Party between 

its armed forces and dissident armed forces or other oiganized armed 

groups which, under responsible command, exercise such control over 

a part of its territory as to enable them to carry out sustained and 

concerted military operations and to implement this Protocol.

Article I further adds that the “Protocol shall not apply to situations of 

internal disturbances and tensions, such as riots, isolated and sporadic acts of 

violence and other acts of a similar nature, as not being armed conflicts.” This is 

true even if the armed forces of the territory may have been called upon to suppress 

the disorder.

It will thus be seen that Protocol II sets down requirements for what it calls 

“material field of application “First, the armed dissidents must be under 

responsible command; second, they must exercise such control over a part of its 

territory as to enable them to carry out sustained and concerted military operations 

and to implement this Protocol.” The Protocol thus sets a very high threshold for 

applicability, higher than the threshold for the applicability of Protocol I which 

does not require control over territory. For this reason, in the conflict between the 

Philippine government and the National Democratic Front, the Philippine 

government has been able to maintain consistently that the NDF and its New 

People’s Army have not crossed this threshold and that therefore what applies to 

them is Common Article 3 and not Protocol II. This means that they do not have 

the status of subject of international law. The same can be said of the MNLF and 

MILF in Mindanao.

Insurgent groups which satisfy the material field of application of Protocol II 

may be regarded as “para-statal entities possessing definite if limited form of 

international personality.” State practice indicates

CHAPTER 6

OTHER SUBJECTS OF INTERNATIONAL LAW

99

two specific attributes of such “personality.” First, they are recognized as having 

belligerent status against the de jure government. Other states are therefore 

required to maintain neutrality regarding them. Second, they are seen as having 

treaty making capacity.

Common Article 3

Traditionally, international law on armed conflict does not apply to internal 

conflicts such as civil wars or rebellions. In 1949, however, it was decided that 

minimum humanitarian protection should also be promulgated to cover internal 

conflict. For this reason, each of the four Geneva Conventions contains a common 

Article 3 which says:

Art. 3. In the case of armed conflict not of an international 

character occurring in the territory of one of the High Contracting 

Parties, each Party to the conflict shall be bound to apply, as a 

minimum, the following provisions:

(1) Persons taking no active part in the hostilities, including 

members of armed forces who have laid down their arms and those 

placed hors de combat by sickness, wounds, detention, or any other 

cause, shall in all circumstances be treated humanely, without any 

adverse distinction founded on race, color, religion or faith, sex, birth 

or wealth, or any other similar criteria.

To this end, the following acts are and shall remain prohibited at 

any time and in any place whatsoever with respect to the abovementioned persons:

(a) violence to life and person, in particular murder of 

all kinds, mutilation, cruel treatment and torture;

(b) taking of hostages;

(c) outrages upon personal dignity, in particular humiliating and degrading treatment;

(d) the passing of sentences and the carrying out of 

executions without previous judgment pronounced by a 

regularly constituted court, affording all the judicial guarantees 

which are recognized as indispensable by civilized peoples.

(2) The wounded and sick shall be collected and cared for.

An impartial humanitarian body, such as the International 

Committee of the Red Cross, may offer its services to the Parties to the 

conflict.

100 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The Parties to the conflict should further endeavor to bring into 

force, by means of special agreements, all or part of the other 

provisions of the present Convention.

The application of the preceding provisions shall not affect the 

legal status of the Parties to the conflict.

The last sentence means that the application does not convert the conflict into 

an international one and therefore does not preclude the possibility that any 

participant in the conflict may be prosecuted for treason. What this means is that, 

although rebels have the protection of Common Article 3, they do not thereby gain 

the status of subjects of international law unless they satisfy the “material field of 

application” of Protocol II.

3. National Liberation Movements.

National liberation movements are organized groups fighting in behalf of a 

whole people for freedom from colonial powers. According to the First Protocol of 

the 1977 Geneva Convention, they are “peoples fighting against colonial 

domination and alien occupation and against racist regimes in the exercise of their 

right of self-determination, as enshrined in the Charter of the United Nations.” They 

first arose in Africa and then in Asia. Many of these movements succeeded in their 

struggle and acquired statehood. Thus, liberation movements are now on the wane.

What are their characteristics. First, they can be based within the territory 

which they are seeking to liberate or they might find a base in a friendly country. 

Control of territory, therefore, is not a necessary factor. Their legitimacy rather 

comes from their goal: to free themselves from colonial domination, or a racist 

regime or foreign occupation. Briefly, their goal is self-determination.

Although control over territory and people is not essential to their legitimacy, 

the ultimate goal of controlling a definite territory is necessary for them to be 

recognized as international subjects. Besides, they must have an organization 

capable of coming into contact with other international organizations. With these 

characteristics, they can claim international status. As Article 96, of the above 

Convention says:

The authority representing a people engaged against a High Con tracting 

Party in an armed conflict of the type referred to in Article 1,

CHAPTER 6

OTHER SUBJECTS OF INTERNATIONAL LAW

101

paragraph 4, may undertake to apply the Conventions and this Protocol in relation 

to that conflict by means of a unilateral declaration addressed to the depositary. 

Such declaration shall, upon its receipt by the depositary, have in relation to that 

conflict the following effects:

(a) The Conventions and this Protocol are brought into force for the 

said authority as a Party to the conflict with immediate effect;

(b) The said authority assumes the same rights and obligations as 

those which have been assumed by a High Contracting Party to the 

Conventions and this Protocol; and

(c) The Conventions and this Protocol are equally binding upon all 

Parties to the conflict.

4. Individuals.

In the early development of international law human beings were exclusively 

under the control of states. In international law they were objects or at best

“beneficiaries” of international law. With the greater global awareness of human 

rights individuals have now come to be recognized as possessing albeit limited 

rights and obligations in international law.

Among the obligations of individuals are those arising from the regulation of 

armed conflicts. Violation of these rules can place individuals under criminal 

responsibility. There are also rules on international crimes to which individuals are 

subject such as crimes against humanity, genocide, aggression, and terrorism. 

When individual rights are violated, however, individuals still have to rely on 

the enforcement power of states. But some treaties have provided for the right of 

individuals to petition international bodies alleging that a contracting state has 

violated some of their human rights.

Antonio Cassese sums up the current situation thus:6

In sum, in contemporary international law individuals possess 

international legal status. They have a few obligations deriving from 

customary international law. In addition, procedural

‘Antonio Cassese, INTERNATIONAL LAW 85, Oxford University Press, 2001. 

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

rights enure to the benefit of individuals not vis-d-vis States, but only 

toward the group of States that have concluded treaties, or the 

international organizations that have adopted resolutions, envisaging 

such rights. Clearly the international legal status of individuals is 

unique: they have a lopsided position in the international community. 

As far as their international obligations are concerned, they are 

associated with all the other members of the international community; 

in contrast, they do not possess rights in relation to all members of that 

community. Plainly, all States are willing to demand of individuals 

respect for some fundamental values, while they are less prepared to 

associate them to their international dealings, let alone to grant them 

the power to sue States before international bodies. To differentiate the 

position of individuals from that of States, it can be maintained that 

while States have international legal personality proper, individuals 

have a limited locus standi in international law. Furthermore, unlike 

States, individual have a limited array of rights and obligations: on this 

score, one can speak of a limited legal capacity (in this respect they 

can be put on the same footing as other non-State international 

subjects: insurgents, international organizations, and national liberation 

movements).

Chapter 7

TERRITORY: LAND, AIR, OUTER SPACE

Territory in International Law.

Territory as an element of a state means an area over which a state has 

effective control. As the Las Palmas case, infra, shows, control over territory is of 

the essence of a state. The exact boundaries might be uncertain, but there should be 

a definitive core over which sovereignty is exercised. Acquisition of territory more 

precisely means acquisition of sovereignty over territory. Judge Huber in the Las 

Palmas case said that “sovereignty over a portion of the surface of the globe is the 

legal condition for the inclusion of such portion in the territory of any particular 

state.”

Territory includes land, maritime areas, airspace and outer space. The scope 

of a state’s jurisdiction over maritime areas will be considered in another chapter. 

In this chapter, only land area, air space and outer space will be considered.

Modes of Acquisition of Sovereignty over Territory.

Some of the questions regarding territory are now of historical interest 

merely. But how they are acquired is still worth examining. The roots of the law on 

territorial sovereignty are traceable to Roman law provisions governing ownership 

and possession. Similarly the classification of the different methods of acquiring 

territory comes from Roman rules of acquiring property. The traditional modes of 

acquisition include discovery and occupation, prescription, cession, conquest and 

subjugation, and accretion.

Discovery and Occupation

Occupation is the acquisition of terra nullius, that is, territory which prior to 

occupation belonged to no state or which may have been

103

104 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

abandoned by a prior occupant. There is abandonment when the occupant leaves 

the territory with the intention of not returning. In the Western Sahara Case,' the 

question was whether Western Sahara, inhabited as it was by organized tribes, was 

terra nullius. The ICJ answered the question thus:

Whatever differences of opinion there may have been among 

jurists, the State practice of the relevant period indicates that territories 

inhabited by tribes or peoples having a social and political 

organization were not regarded as terra nullius.

It shows that in the case of such territories the acquisition of 

sovereignty was not generally considered as effected unilaterally 

through “occupation” of terra nullius by original title but through 

agreements concluded with local rulers. On occasion, it is true, the 

word “occupation” was used in a non-technical sense denoting simply 

acquisition of sovereignty; but that did not signify that the acquisition 

of sovereignty through such agreements with authorities of the country 

was regarded as an “occupation” of a “terra nullius” in the proper 

sense of these terms. On the contrary, such agreements with local 

rulers, whether or not considered as an actual “cession” of the 

territory, were regarded as derivative roots of title, and not original

titles obtained by occupation of terra nullius.

In the present instance, the information furnished to the Court 

shows that at the time of colonization Western Sahara was inhabited 

by peoples which, if nomadic, were socially and politically organized 

into tribes and under chiefs competent to represent them.

Discovery of terra nullius, moreover, is not enough to establish sovereignty. 

It must be accompanied by effective control. This is the teaching of the Las Palmas 

Case.

THE ISLAND OF PALMAS

Perm. Ct. Arb. (1928)

(Abridged)

Background. Palmas (also referred to as Miangas) is an 

island about two miles long by three fourths of a mile wide 

which at the time of this case had a population of about 750 and 

was of little strategic or economic value. It sits

'Advisory Opinion, ICJ, 1975.

CHAPTER 7

TERRITORY: LAND, AIR, OUTER SPACE

about halfway between the islands of Mindanao in the Philippines and Nanusa in the Netherlands Indies. It is, however, 

within the boundaries of the Philippines as defined by Spain and 

thus ceded to the United States in 1898. In 1906 an American 

General, Leonard Wood, visited Palmas and discovered that the 

Netherlands also claimed sovereignty over the island. An 

agreement was signed on January 23, 1925, between the United 

States and the Netherlands to submit the dispute to binding 

arbitration. The Swiss jurist, Max Huber, was the selected 

arbitrator acting for the Permanent Court of Arbitration. Huber 

was charged to determine “whether the Island of Palmas” (or 

Miangas) in its entirety forms a part of territory belonging to the 

United States of America or of Netherlands territory.

HUBER, Arbitrator:

The United States, as successor to the rights of Spain over the 

Philippines, bases its title in the first place on discovery. The existence 

of sovereignty thus acquired is, in the American view, confirmed not 

merely by the most reliable cartographers and authors, but also by 

treaty, in particular by the Treaty of Munster, of 1648, to which Spain 

and the Netherlands are themselves Contracting Parties. As, according 

to the same argument, nothing has occurred of a nature, in 

international law, to cause the acquired title to disappear, this latter 

title was intact at the moment when, by the Treaty of December 10th, 

1898, Spain ceded the Philippines to the United States. In these 

circumstances, it is, in the American view, unnecessary to establish 

facts showing the actual display of sovereignty precisely over the 

Island of Palmas (or Miangas). The United States Government finally 

maintains that Palmas (or Miangas) forms a geographical part of the 

Philippine group and in virtue of the principle of contiguity belongs to 

the Power having the sovereignty over the Philippines. ...

Sovereignty in the relation between States signifies 

independence. Independence in regard to a portion of the globe is the 

right to exercise therein, to the exclusion of any other State, the 

functions of a State. The development of the national organization of 

States during the last few centuries and, as a corollary, the 

development of international law, have established this principle of the 

exclusive competence of the State in regard to its own territory in such 

a way as to make it the point of departure in settling most questions 

that concern international relations. ...

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Titles of acquisition of territorial sovereignty in present- day 

international law are either based on an act of effective apprehension, 

such as occupation or conquest, or, like cession, presuppose that the 

ceding and the cessionary Power or at least one of them, have the 

faculty of effectively disposing of the ceded territory. In the same way 

natural accretion can only be conceived of as an accretion to a portion 

of territory where there exists an actual sovereignty capable of 

extending to a spot which falls within its sphere of activity. It seems 

therefore natural that an element which is essential for the constitution 

of sovereignty should not be lacking in its continuation. So true is this, 

that practice, as well as doctrine, recognizes — though under different 

legal formulae and with certain differences as to the conditions 

required — that the continuous and peaceful display of territorial 

sovereignty (peaceful in relation to other States) is as good as a title. 

The growing insistence with which international law, ever since the 

middle of the 18th century, has demanded that the occupation shall be 

effective would be inconceivable, if effectiveness were required only 

for the act of acquisition and not equally for the maintenance of the 

right....

Territorial sovereignty, as has already been said, involves the 

exclusive right to display the activities of a state. This right has as 

corollary a duty: the obligation to protect within the territory the rights 

of other states, in particular their right to integrity and inviolability in 

peace and in war, together with the rights which each state may claim 

for its nationals in foreign territory. Without manifesting its territorial 

sovereignty in a manner corresponding to circumstances, the state 

cannot fulfill this duty. Territorial sovereignty cannot limit itself to its 

negative side, i.e., to excluding the activities of other states; for it 

serves to divide between nations the space upon which human 

activities are employed, in order to assure them at all points the 

minimum of protection of which international law is the guardian....

The principle that continuous and peaceful display of the 

functions of state within a given region is a constituent element of 

territorial sovereignty is not only based on the conditions of the 

formation of independent states and their boundaries (as shown by the 

experience of political history) as well as on an international 

jurisprudence and doctrine widely accepted; this principle has further 

been recognized in more than one federal state, where a jurisdiction is 

established in order to apply, as need arises, rules of international law 

to the interstate relations of the states members.

CHAPTER 7

TERRITORY: LAND, AIR, OUTER SPACE

Manifestations of territorial sovereignty assume, it is true, 

different forms, according to conditions of time and place. Although 

continuous in principle, sovereignty cannot be exercised in fact at 

every moment on every point of territory. The intermittence and 

discontinuity compatible with the maintenance of the right necessarily 

differ according as inhabited or uninhabited regions are involved, or 

regions enclosed within territories in which sovereignty is 

incontestably displayed or again regions accessible from, for instance, 

the high seas. It is true that neighboring states may by convention fix 

limits to their own sovereignty, even in regions such as the interior of 

scarcely explored continents where such sovereignty is scarcely 

manifested, and in this way each may prevent the other from any 

penetration of its territory. The delimitation of hinterland may also be 

mentioned in this connection....

The title alleged by the United States of America as constituting 

the immediate foundation of its claim is that of cession, brought about

by the Treaty of Paris, which cession transferred all rights of 

sovereignty which Spain may have possessed in the region indicated in 

Article III of the said Treaty and therefore also those concerning the 

Island of Palmas (or Miangas).

It is evident that Spain could not transfer more rights than she 

herself possessed....

It is recognized that the United States communicated, on 

February 3rd, 1899, the Treaty of Paris to the Netherlands, and that no 

reservations were made by the latter in respect of the delimitation of 

the Philippines in Article III. The question whether the silence of a 

third Power, in regard to a treaty notified to it, can exercise any 

influence on the rights of this Power, or on those of the Powers 

signatories of the treaty, is a question the answer to which may depend 

on the nature of such rights. Whilst it is conceivable that a 

conventional delimitation duly notified to third Powers and left 

without contestation on their part may have some bearing on an 

inchoate title not supported by any actual display of sovereignty, it 

would be entirely contrary to the principles laid down above as to 

territorial sovereignty to suppose that such sovereignty could be 

affected by the mere silence of the territorial sovereign as regards a 

treaty which has been notified to him and which seems to dispose of a 

part of his territory....

In any case for the purpose of the present affair it may be 

admitted that the original title derived from discovery belonged to 

Spain....

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

If the view most favorable to the American arguments is 

adopted — with every reservation as to the soundness of such view —

that is to say, if we consider as positive law at the period in question 

the rule that discovery as such, i.e., the mere fact of seeing land, 

without any act, even symbolical, of taking possession, involved ipso 

jure territorial sovereignty and not merely an “Inchoate title,” a jus ad 

rem, to be completed eventually by an actual and durable taking of 

possession within a reasonable time, the question arises whether 

sovereignty yet existed at the critical date, i.e., the moment of 

conclusion and coming into force of the Treaty of Paris.

As regards the question which of different legal systems 

prevailing at successive periods is to be applied in a particular case 

(the so-called inter-temporal law), a distinction must be made between 

the creation of rights and the existence of rights. The same principle 

which subjects the act creative of a right to the law in force at the time 

the right arises, demands that the existence of the right, in other words 

its continued manifestation, shall follow the conditions required by the 

evolution of law. International law in the 19th century, having regard 

to the fact that most parts of the globe were under the sovereignty of 

states members of the community of nations, and that territories 

without a master had become relatively few, took account of a 

tendency already existing and especially developed since the middle 

of the 18th century, and laid down the principle that occupation, to 

constitute a claim to territorial sovereignty, must be effective, that is, 

offer certain guarantees to other states and their nationals. It seems 

therefore incompatible with this rule of positive law that there should 

be regions which are neither under the effective sovereignty of a state, 

nor without a master, but which are reserved for the exclusive 

influence of one state, in virtue solely of a title of acquisition which is 

no longer recognized by existing law, even if such a title ever 

conferred territorial sovereignty. For these reasons, discovery alone, 

without any subsequent act, cannot at the present time suffice to prove 

sovereignty over the Island of Palmas (or Miangas); and in so far as 

there is no sovereignty, the question of an abandonment properly 

speaking of sovereignty by one state in order that the sovereignty of 

another may take its place does not arise.

... [E]ven admitting that the Spanish title still existed as 

inchoate in 1898 and must be considered as included in the cession 

under Article III of the Treaty of Paris, an inchoate title could not 

prevail over the continuous and peaceful display of authority

CHAPTER 7

TERRITORY: LAND, AIR, OUTER SPACE

by another state; for such display may prevail even over a prior, 

definitive title put forward by another state. This point will be 

considered, when the Netherlands argument has been examined and 

the allegations of either party as to the display of their authority can be 

compared....

In the last place there remains to be considered title arising out 

of contiguity. Although states have in certain circumstances 

maintained that islands relatively close to their shores belonged to 

them in virtue of their geographical situation, it is impossible to show 

the existence of a rule of positive international law to the effect that 

islands situated outside territorial waters should belong to a state from 

the mere fact that its territory forms the terra firma (nearest continent 

or island of considerable size). Not only would it seem that there are 

no precedents sufficiently frequent and sufficiently precise in their 

bearing to establish such a rule of international law, but the alleged 

principle itself is by its very nature so uncertain and contested that 

even governments of the same state have on different occasions 

maintained contradictory opinions as to its soundness. The principle of 

contiguity, in regard to islands, may not be out of place when it is a 

question of allotting them to one state rather than another, either by 

agreement between the parties, or by a decision not necessarily based 

on law; but as a rule establishing ipso jure the presumption of 

sovereignty in favor of a particular state, this principle would be in 

conflict with what has been said as to territorial sovereignty and as to 

the necessary relation between the right to exclude other states from a 

region and the duty to display therein the activities of a state. Nor is 

this principle of contiguity admissible as a legal method of deciding 

questions of territorial sovereignty; for it is wholly lacking in precision 

and would in its application lead to arbitrary results. This would be 

especially true in a case such as that of the island in question, which is 

not relatively close to one single continent, but forms part of a large 

archipelago in which strict delimitations between the different parts are 

not naturally obvious....

It is, however, to be observed that international arbitral 

jurisprudence in disputes on territorial sovereignty (e.g., the award in 

the arbitration between Italy and Switzerland concerning the Alpe 

Craivarola; Lafontaine, Pasicrisie international, pp. 201- 209) would 

seem to attribute greater weight to — even isolated

— acts of display of sovereignty than to continuity of territory, even if 

such continuity is combined with the existence of natural boundaries....

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

In the opinion of the Arbitrator the Netherlands have succeeded 

in establishing the following facts:

a. The Island of Palmas (or Miangas) Is identical with 

an island designated by this or a similar name, which has 

formed, at least since 1700, successively a part of two of the 

native States of the Island of Sangi (Talautse Isles).

b. These native States were from 1677 onwards 

connected with the East India Company, and thereby with the 

Netherlands, by contracts of suzerainty, which conferred upon 

the suzerain such powers as would ‘justify his considering the 

vassal state as a part of his territory.’

c. Acts characteristic of state authority exercised 

either by the vassal state or by the suzerain Power in regard

precisely to the Island of Palmas (or Miangas) have been 

established as occurring at different epochs between 1700 and 

1898, as well as in the period between 1898 and 1906.

The acts of indirect or direct display of Netherlands sovereignty 

at Palmas (or Miangas), especially in the 18th and early 19th centuries 

are not numerous, and there are considerable gaps in the evidence of 

continuous display. But apart from the consideration that the 

manifestations of sovereignty over a small and distant island, inhabited 

only by natives, cannot be expected to be frequent, it is not necessary 

that the display of sovereignty should go back to a very far distant 

period. It may suffice that such display existed in 1898, and had 

already existed as continuous and peaceful before that date long 

enough to enable any Power who might have considered herself as 

possessing sovereignty over the island, or having a claim to 

sovereignty, to have, according to local conditions, a reasonable 

possibility for ascertaining the existence of a state of things contrary to 

her real or alleged rights....

There is moreover no evidence which would establish any act of 

display of sovereignty over the island by Spain or another Power, such 

as might counterbalance or annihilate the manifestations of 

Netherlands sovereignty. As to third Powers, the evidence submitted to 

the Tribunal does not disclose any trace of such action, at least from 

the middle of the 17th century onwards. These circumstances, together 

with the absence of any evidence of a conflict between Spanish and 

Netherlands authorities during more than two centuries as regards 

Palmas (or Miangas), are an indirect proof of the exclusive display of 

Netherlands sovereignty....

CHAPTER 7

TERRITORY: LAND, AIR, OUTER SPACE

111

The conditions of acquisition of sovereignty by the Netherlands 

are therefore to be considered as fulfilled. It remains now to be seen 

whether the United States as successors of Spain are in a position to 

bring forward an equivalent or stronger title. This is to be answered in 

the negative.

The title of discovery, if it had not already been disposed of by 

the Treaties of Munster and Utrecht, would, under the most favorable 

and most extensive interpretation, exist only as an inchoate title, as a 

claim to establish sovereignty by effective occupation. An inchoate 

title however cannot prevail over a definite title founded on continuous 

and peaceful display of sovereignty.

The title of contiguity, understood as a basis of territorial 

sovereignty, has no foundation in international law....

The Netherlands title of sovereignty, acquired by continuous and 

peaceful display of state authority during a long period of time going 

probably back beyond the year 1700, therefore holds good....

For these reasons the Arbitrator ... decides that: The Island of 

Palmas (or Miangas) forms in its entirety a part of Netherlands 

territory.

Effective control, however, is relative and may depend on the nature of the 

case — e.g., whether the territory is inhabited or not and how fierce the occupants 

are. Where there are two or more claimants to a territory, effective control is also 

relative to the strength of claims. (Eastern Greenland Case PCIJ 1933) The 

Permanent Court of Justice deciding in favor of Denmark, said:

Before proceeding to consider in detail the evidence submitted 

to the Court, it may be well to state that a claim to sovereignty based 

not upon some particular act or title such as a treaty of cession but 

merely upon continued display of authority, involves two elements 

each of which must be shown to exist: the intention and will to act as 

sovereign, and some actual exercise or display of such authority.

Another circumstance which must be taken into account by any 

tribunal which has to adjudicate upon a claim to sovereignty over a 

particular territory, is the extent to which the sovereignty is also 

claimed by some other Power. In most of the cases involving claims to 

territorial sovereignty which have come before an international 

tribunal, there have been two competing claims to the

112 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

sovereignty, and the tribunal has had to decide which of the two is the 

stronger. One of the peculiar features of the present case is that up to 

1931 there was no claim by any Power other than Denmark to the 

sovereignty over Greenland. Indeed, up till 1921, no Power disputed 

the Danish claim to sovereignty.

It is impossible to read the records of the decisions in cases as to 

territorial sovereignty without observing that in many cases the 

tribunal has been satisfied with very little in the way of the actual 

exercise of sovereign rights, provided that the other State could not 

make out a superior claim. This is particularly true in the case of 

claims to sovereignty over areas in thinly populated or unsettled 

countries.

Prescription

Prescription is also recognized as a mode of acquiring sovereignty over 

territory. Like occupation, however, prescription requires effective control. But 

unlike occupation, the object of prescription is not terra nullius. Thus the required 

length of effective control is longer than in occupation. Moreover, prescription 

might be negated by a demonstrated lack of acquiescence by the prior occupant. 

(Las Palmas)

Cession

Cession, or acquisition of territory through treaty, is another mode. Thus the 

United States acquired the Philippines through the Treaty of Paris. Sovereignty 

over Hong Kong is a more recent example of cession. In the middle of the 19th 

century, part of the colony of Hong Kong was ceded in perpetuity to Britain. The 

largest section of the colony, the so called New Territories, was merely held under 

a lease that was due to expire in 1997. After protracted negotiations, a Joint 

Declaration was signed through which the entire territory of Hong Kong would be 

given over to the sovereignty of China on July 1,1997. This has already been 

accomplished.

It should also be noted, however, that a treaty of cession which is imposed by 

a conqueror is invalid. Thus there may be a situation where what prevails is merely 

a de facto regime.

Conquest

Conquest was in earlier days the taking possession of a territory through 

armed force. For acquisition of conquered territory, it was

CHAPTER 7

TERRITORY: LAND, AIR, OUTER SPACE

113

necessary that the war had ended either by treaty or by indication that all resistance 

had been abandoned. Moreover, the conqueror must have had the intention of 

acquiring the territory and not just of occupying it temporarily. For instance, the 

U.S. in Germany had no intention of acquiring the territory.

Today conquest as a mode of acquisition is proscribed by international law. 

The 1970 Declaration of Principles of International Law Concerning Friendly 

Relations and Cooperation among States has this to say: “The territory of a State 

shall not be the object of acquisition by another State resulting from the threat or 

use of force. No territorial acquisition resulting from the use or threat of force shall 

be recognized as legal.”

The latest instance of a response to an attempted conquest was the action 

taken against Iraq when it invaded Kuwait.

Accretion and Avulsion

Accretion and avulsion can also lead to sovereignty over territory. This is 

sovereignty by operation of nature. Accretion is the gradual increase of territory by 

the action of nature; avulsion is a sudden change resulting for instance from the 

action of a volcano.

Is contiguity a mode of acquisition?

Because of the closeness of the Spratleys to Philippine territory, it has been 

argued that the area belongs to the Philippines by contiguity. The Las Palmas case 

is argument against contiguity as a basis for sovereignty when it says: “it is 

impossible to show a rule of positive international law to the effect that islands 

situated outside the territorial waters should belong to a state from the fact that its 

territory forms part of the terra frma.”

Intertemporal Law

Laws on acquisition of territory have changed. Note for instance the changes 

on the legality of wars of conquest. Which laws then are applicable to a 

controversy? The generally accepted view is that the rules in effect at the time of 

the acquisition should be applied.

114 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Airspace.

Before the First World War, there were those who held that the airspace was 

completely free. The outbreak of the First World War brought about the realization 

that the use of the air had security implications. Out of this realization came the 

approach which considers the air above as an extension of the territory below. Each 

state has exclusive jurisdiction over the air space above its territory. Therefore, 

consent for transit must be obtained from the subjacent nation.

The present regime on air navigation has developed from the Chicago 

Convention on International Civil Aviation (1944) which entered into force in 

1974. The Chicago Convention created the International Civil Aviation 

Organization (ICAO), an agency of the United Nations, and prescribed the rules for

international civil aviation.

Articles 1 to 4 of the Convention set down the governing principles:

Article 1. Sovereignty

The contracting States recognize that every State has complete 

and exclusive sovereignty over the airspace above its territory.

Article 2. Territory

For the purposes of this Convention the territory of a State shall 

be deemed to be the land areas and territorial waters adjacent thereto 

under the sovereignty, suzerainty, protection or mandate of such State.

Article 3. Civil and state aircraft

(a) This Convention shall be applicable only to civil aircraft, 

and shall not be applicable to state aircraft.

(b) Aircraft used in military, customs and police services 

shall be deemed to be state aircraft.

(c) No state aircraft of a contracting State shall fly over the 

territory of another State or land thereon without authorization by 

special agreement or otherwise, and in accordance with the terms 

thereof.

(d) The contracting States undertake, when issuing regulations for their state aircraft, that they will have due regard for the 

safety of navigation of civil aircraft.

CHAPTER 7

TERRITORY: LAND, AIR, OUTER SPACE

115

Article 4. Misuse of civil aviation

Each contracting State agrees not to use civil aviation for any 

purpose inconsistent with the aims of this Convention.

As can be seen, the Convention does deal with “state aircraft” excepted to say 

in Article 3(a) that “No state aircraft of a contracting State shall fly over the 

territory of another State or land thereon without authorization by special agreement 

or otherwise, and in accordance with the terms thereof.” And “state aircraft”

means “aircraft used in military, customs and police services.” The Convention is 

about “civil aviation.”

Flight over territory is classified into “non-scheduled” and “scheduled” 

fights.

Article 5. Right of non-scheduled flight

Each contracting State agrees that all aircraft of the other 

contracting States, being aircraft not engaged in scheduled international air services shall have the right, subject to the observance of the 

terms of this Convention, to make flights into or in transit nonstop 

across its territory and to make stops for non-traffic purposes without 

the necessity of obtaining prior permission, and subject to the right of 

the State flown over to require landing. Each contracting State 

nevertheless reserves the right, for reasons of safety of flight, to require 

aircraft desiring to proceed over regions which are inaccessible or 

without adequate air navigation facilities to follow prescribed routes, 

or to obtain special permission for such flights.

Such aircraft, if engaged in the carriage of passengers, cargo, or 

mail for remuneration or hire on other than scheduled international air 

services, shall also, subject to the provisions of Article 7, have the 

privilege of taking on or discharging passengers, cargo, or mail, 

subject to the right of any State where such embarkation or discharge 

takes place to impose such regulations, conditions or limitations as it 

may consider desirable.

Article 6. Scheduled air services

No scheduled international air service may be operated over or 

into the territory of a contracting State, except with the special 

permission or other authorization of that State, and in accordance with

the terms of such permission or authorization.

J16 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Article 7. Cabotage

Each contracting State shall have the right to refuse 

permission to the aircraft of other contracting States to take on in its 

territory passengers, mail and cargo carried for remuneration or hire 

and destined for another point within its territory. Each contracting 

State undertakes not to enter into any arrangements which specifically 

grant any such privilege on an exclusive basis to any other State or an 

airline of any other State, and not to obtain any such exclusive 

privilege from any other State.

The Chicago Convention attempts to provide protection for civilian aircraft. 

Since the Convention, however, a number of incidents have taken place fatal to 

civilian aircraft. In 1955 a civilian Israeli plane of El A1 Israel Airlines was shot 

down by Bulgaria. In 1973, Israeli jets shot down a straying Libyan airliner. In 

1983, Russian jets shot down a Korean Airlines plane. When the United States 

made the declaration in the Security Council that “sovereignty neither requires nor 

permits the shooting down of airlines in peacetime,” the USSR’s swift reply was 

that there was a sovereign right of every State to protect its borders including its 

airspace.

In 1953, Lissitzyn2

suggested a flexible rule with respect at least to state or 

military aircraft: “In its effort to control the movements of intruding aircraft the 

territorial sovereignty must not expose the aircraft and its occupants to unnecessary 

and unreasonably great danger — that is, in relation to the apprehended 

harmfulness of the intrusion.” This implies that the aircraft must not only not be 

attacked, unless there is reason to suspect that the aircraft is a real threat, but also 

that a warning to land or change course must be given before it is attacked. As to 

civilian aircraft, however, there are those who hold that civilian aircraft should 

never be attacked. In fact, even the Soviet Union justified its attack on the South 

Korean airliner by saying that it had mistaken the aircraft for an American 

reconnaissance aircraft.

Outer Space.

The assertion under air space law used to be that air sovereignty extended to 

an unlimited extent, usque ad coelum. The development

2AJIL47 (1953) 559.

CHAPTER 7

TERRITORY: LAND, AIR, OUTER SPACE

117

of the law on outer space modified this assertion. Sovereignty over air space 

extends only until where outer space begins. But where is that?

There is as yet no definite answer to that question. The answer will 

eventually come from technological capabilities of conventional aircraft to reach 

greater heights. Different numbers ranging from fifty to one hundred miles from the 

earth have been mentioned. Nonetheless, the development of outer space law has 

started. It is now accepted that outer space, wherever that might be, and celestial 

bodies, are not susceptible to appropriation by any state. Among the first 

achievements in this area is the 1967 Treaty on the Exploration and Use of Outer 

Space. Some of its key provisions are the following:

Article I. The exploration and use of outer space, including the 

moon and other celestial bodies, shall be carried out for the benefit and 

in the interests of all countries, irrespective of their degree of economic 

or scientific development, and shall be the province of all mankind. 

Outer space, including the moon and other celestial bodies, shall be 

free for exploration and use by all States without discrimination of any 

kind, on a basis of equality and in accordance with international law, 

and there shall be free access to all areas of celestial bodies. There 

shall be freedom of scientific investigation in outer space, including 

the moon and other celestial bodies, and States shall facilitate and 

encourage international co-operation in such investigation.

Article 11. Outer space, including the moon and other celestial 

bodies, is not subject to national appropriation by claim of sovereignty, 

by means of use or occupation, or by any other means.

Article III. States Parties to the Treaty shall carry on activities in 

the exploration and use of outer space, including the moon and other 

celestial bodies, in accordance with international law, including the 

Charter of the United Nations, in the interest of maintaining 

international peace and security and promoting international cooperation and understanding.

Article IV. States Parties to the Treaty undertake not to place in 

orbit around the Earth any objects carrying nuclear weapons or any 

other kinds of weapons of mass destruction, install such weapons on 

celestial bodies, or station such weapons in outer space in any other 

manner.

The Moon and other celestial bodies shall be used by all States 

Parties to the Treaty exclusively for peaceful purposes. The

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

establishment of military bases, installations and fortifications, the 

testing of any type of weapons and the conduct of military maneuvers 

on celestial bodies shall be forbidden. The use of military personnel 

for scientific research or for any other peaceful purposes shall not be 

prohibited. The use of any equipment or facility necessary for peaceful 

exploration of the Moon and other celestial bodies shall also not be 

prohibited.

Article V. States Parties to the Treaty shall regard astronauts as 

envoys of mankind in outer space and shall render to them all possible 

assistance in the event of accident, distress, or emergency landing on 

the territory of another State Party or on the high seas. When 

astronauts make such a landing, they shall be safely and promptly 

returned to the State of registry of their space vehicle.

In carrying on activities in outer space and on celestial bodies, 

the astronauts of one State Party shall render all possible assistance to 

the astronauts of other States Parties. States Parties to the Treaty shall 

immediately inform the other States Parties to the Treaty or the 

Secretary-General of the United Nations of any phenomena they 

discover in outer space, including the Moon and other celestial bodies, 

which could constitute a danger to the life or health of astronauts.

Chapter 8 TERRITORY: LAW OF THE SEA

The importance of the seas flows from two factors: first, they are a medium 

of communication, and second, they contain vast natural resources. In the 17th 

century, the Portuguese proclaimed vast areas of sea as belonging to itself. But it 

was Grotius who elaborated the doctrine of the open seas which considers the high 

seas as res communis accessible to all. The doctrine, however, recognized as 

permissible the delineation of a maritime belt by littoral states as an indivisible part 

of its domain. This belt is the territorial sea.

Much of the history of the law of the sea has centered around the extent of 

the territorial sea. But over the years, other jurisdictional issues have occurred and 

today the prevailing law on maritime domain is the Convention on the Law of the 

Sea of 1982 (LOS). Many of the provisions of the 1982 Law of the Sea are a 

repetition of earlier convention law or a codification of customary law.

The basic statement of the extent of a state’s sovereignty over waters is set 

down in Article 2 of the 1982 Law of the Sea:

Article 2. Legal status of the territorial sea, of the air space 

over the territorial sea and of its bed and subsoil.

1. The sovereignty of a coastal State extends, beyond its 

land territory and internal waters and, in the case of an archipelagic

State, its archipelagic waters, to an adjacent belt of sea, described as 

the territorial sea.

2. This sovereignty extends to the air space over the territorial sea as well as to its bed and subsoil.

3. The sovereignty over the territorial sea is exercised 

subject to this Convention and to other rules of international law.

119

120 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Territorial sea.

The territorial sea is a belt of sea outwards from the baseline and up to 12 

nautical miles beyond. The width of this territorial belt of water has been the 

subject of much disagreement. The original rule was the “cannon shot” rule, that 

is, the width of water was measured in terms of the range of shore-based artillery. 

Later this became the three-mile rule. The three mile rule has now been discarded 

in favor of the twelve-mile rule now found in Article 3 of the 1982 LOS.

Where, however, the application of the twelve-mile rule to neighboring 

littoral states would result in overlapping, the rule now established is that the 

dividing line is a median line equidistant from the opposite baselines. But the 

equidistance rule does not apply where historic title or other special circumstances

require a different measurement. Article 15,1982 LOS.

Baselines: “normal" or “straight"

To understand the extent of the territorial sea one must begin with an 

understanding of baselines. The baseline is “the low-water line along the coast as 

marked on large scale charts officially recognized by the coastal State.” (Section 

5,182 LOS) The width of the territorial sea is measured from the baseline.

There are two ways of drawing the baseline. The “normal” baseline is one 

drawn following “the low-water line along the coast as marked on large-scale 

charts officially recognized by the coastal State.”' This line follows the curvatures 

of the coast and therefore would normally not consist of straight lines.

There is no fixed norm for determining the “low water mark” but the AngloNorwegian Fisheries Case (U.K. v. Norway ICJ 1951) has suggested that “for the 

purpose of measuring the breadth of the territorial sea, it is the low-water mark as 

opposed to the high-water mark, or the mean between the two tides, which has 

generally been adopted in the practice of States. This criterion is the most 

favorable to the coastal State and clearly shows the character of territorial waters 

as appurtenant to the land territory.”2

'Article 5, Law of the 

2

1951 ICJ 116,128.

CHAPTER 8

TERRITORY: LAW OF THE SEA

121

Archipelagic states, however, instead of drawing “normal baselines,” have 

drawn “straight baselines.” Instead of following the curvatures of the coast, 

straight lines are drawn connecting selected points on the coast without 

appreciable departure from the general shape of the coast. This method of drawing 

lines was first upheld in the Anglo-Nor- wegian Fisheries Case3 which upheld the 

straight baseline unilaterally adopted by Norway. Likewise, R.A. No. 3046 and 

R.A. No. 5446 have drawn “straight baselines” around the Philippines.

The decision in the Fisheries Case upholding the “straight baseline 

method” eventually became part of convention law. Article 7(1) of the Convention 

on the Law of the Sea says: “In localities where the coastline is deeply indented 

and cut into, or if there is a fringe of islands along the coast in its immediate 

vicinity, the method of straight baselines joining appropriate points may be 

employed in drawing the baseline from which the breadth of the territorial sea is 

measured.”4

Article 47 of the Convention on the Law of the Sea allows the use of the 

“straight baseline method” for archipelagic states with certain limitations. The 

article in full reads:

1. An archipelagic State may draw straight archipelagic 

baselines joining the outermost points of the outermost islands and

drying reefs of the archipelago provided that within such baselines are 

included the main islands and an area in which the ratio of the area of 

the water to the area of the land, including atolls, is between 1 to 1

and 9 to 1.

2. The length of such baseline shall not exceed 100 nautical 

miles, except that up to 3 percent of the total number of baselines 

enclosing any archipelago may exceed that length, up to a maximum 

length of 125 nautical miles.

3. The drawing of such baselines shall not depart to any 

appreciable extent from the general configuration of the archipelago4. Such baselines shall not be drawn to and from low- tide 

elevations, unless lighthouses or similar installations which are 

permanently above sea level have been built on them or where

3

1951 ICJ at 130. The argument from this case is by analogy and, therefore, only as strong as the 

analogy. See Committee Report No. 01 and Speech of Delegate Laggui, Session of February 14,1972.

'See also 1958 Territorial Sea Convention.

122 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

a low-tide elevation is situated wholly or partially at a distance not 

exceeding the breadth of the territorial sea of another State.

5. The system of such baselines shall not be applied to an 

archipelagic State in such a manner as to cut-off from the high seas or 

the exclusive economic zone the territorial sea of another State.

6. If a part of the archipelagic waters of an archipelagic 

State lies between two parts of an immediately adjacent neighboring 

State, existing rights and all other legitimate interests which the latter 

State has traditionally exercised in such waters and all rights 

stipulated by agreement between those States shall continue and be 

respected.

7. F

or the purpose of computing the ratio of water to land under 

paragraph 1, land areas may include waters lying within the hinging 

reefs of islands and atolls, including that part of a steepsided oceanic 

plateau which is enclosed or nearly enclosed by a chain of limestone 

islands and drying reefs lying on the perimeter of the plateau.

8. The baselines drawn in accordance with this article shall 

be shown on charts of a scale or scales adequate for ascertaining their 

position. Alternatively, lists of geographical co-ordinates of points, 

specifying the geodetic datum, may be substituted.

9. The archipelagic State shall give due publicity to such 

charts or lists of geographical co-ordinates and shall deposit a copy of 

each such chart or list with the Secretary-General of the United 

Nations.

Sovereignty over Territorial Sea

The sovereignty of the coastal state over its territorial sea and the airspace 

above it as well as the seabed under is the same as its sovereignty over its land 

territory. (Article 2, LOS) However, the sea is subject to the right of innocent 

passage by other states. The rule on innocent passage applies to ships and aircraft. 

Submarines, moreover, must surface.

Innocent passage is passage that is not prejudicial to the peace, good order 

or security of the coastal state. Article 19(2) enumerates acts that are not 

considered innocent passage thus:

2. Passage of a foreign ship shall be considered to be 

prejudicial to the peace, good order or security of the coastal State if 

in the territorial sea it engages in any of the following activities:

CHAPTER 8

TERRITORY: LAW OF THE SEA

123

(a) any threat or use of force against the sovereignty, 

territorial integrity or political independence of the coastal 

State, or in any other manner in violation of the principles of 

international law embodied in the Charter of the United 

Nations;

(b) any exercise or practice with weapons of any

kind;

(c) any act 

aimed at collecting information to the

prejudice of the defense or security of the coastal State;

(d) any act of 

propaganda aimed at affecting the

defense or security of the coastal State;

(e) the launching, landing or taking on board of any 

aircraft;

(f) the 

launching, landing or taking on board of any

military device;

(g) the loading or unloading of any commodity, currency or person contrary to the customs, fiscal, immigration or 

sanitary laws and regulations of the coastal State;

(h) any act of willful and serious pollution contrary to 

this Convention;

(i) any fishing 

activities;

(j) the carrying out of research or survey activities;

(k) any act aimed at interfering with any systems of 

communication or any other facilities or installations of the 

coastal State;

(1) any other activity not having a direct bearing on 

passage.

Coastal states have the unilateral right to verify the innocent character of 

passage, and it may take the necessary steps to prevent passage that it determines 

to be not innocent.

The rule on innocent passage is also applicable to straits. In the Corfu 

Channel Case,5

the Court said:

It is, in the opinion of the Court, generally recognized and in 

accordance with international custom that States in time of peace

5UJC. v. Albania, [1949] ICJ Rep.

124 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

have a right to send their warships through straits used for international navigation between two parts of the high seas without the 

previous authorization of a coastal State, provided that the passage is 

innocent. Unless otherwise prescribed in an international convention, 

there is no right for a coastal State to prohibit such passage through 

straits in time of peace.

This rule is now found in Article 45 of the 1982 Convention.

Internal waters.

Internal waters are all waters (part of the sea, rivers, lakes, etc.) landwards 

from the baseline of the territory. Sovereignty over these waters is the same in 

extent as sovereignty over land, and it is not subject to the right of innocent 

passage. However, in Saudi Arabia v. Aramco (Arbitration 1963), the arbitrator 

said that according to international law — ports of every state must be open to 

foreign vessels and can only be closed when vital interests of the state so requires. 

But according to the Nicaragua v. US.,6

a coastal state may regulate access to its 

ports.

Archipelagic waters.

Article 8(2) of the Convention which says: “Where the establishment of a 

straight baseline in accordance with the method set forth in Article 7 has the effect 

of enclosing as internal waters areas which had not previously been considered as 

such, a right of innocent passage as provided in this Convention shall exist in 

those waters.” Article 53 of the Convention refers to this type of internal water as 

“archipelagic waters” and says that “[a]n archipelagic State may designate sea 

lanes and air routes thereabove, suitable for the continuous and expeditious 

passage of foreign ships and aircraft through or over its archipelagic waters and 

the adjacent territorial sea.”

This provision was seen as posing a problem for Philippine law because 

Article I of the Philippine Constitution, which took effect in 1973 prior to the 

1982 Convention on the Law of the Sea, considers all waters connecting the 

islands as internal waters. The Philippine government was clearly aware of these 

possible conflicts. Hence, upon its

125

ratification of the Convention on the Law of the Sea on August 5,1984, it added 

the following declaration:7

1. The signing of the Convention by the Government of the 

Republic of the Philippines shall not in any manner impair or prejudice the 

sovereign rights of the Republic of the Philippines under and arising from 

the Constitution of the Philippines;

2. Such signing shall not in any manner affect the sovereign rights 

of the Republic of the Philippines as successor to the United States of 

America, under and arising out of the Treaty of Paris between Spain and the 

United States of America of December 10, 1988, and the Treaty of 

Washington between the United States of America and Great Britain of

January 2,1930;

3. Such signing shall not diminish or in any manner affect the 

rights and obligations of the Contracting Parties under the Mutual Defense 

Treaty between the Philippines and the United States of America of August 

30,1951, and its related interpretative instruments; nor those under any 

pertinent bilateral or multilateral treaty or agreement to which the 

Philippines is a party;

6. The provisions of the Convention on archipelagic passage 

through sea lanes do not nullify or impair the sovereignty of the Philippines 

as an archipelagic State over the sea lanes and do not deprive it of authority 

to enact legislation to protect its sovereignty, independence, and security;

7. The concept of archipelagic waters is similar to the concept of 

internal waters under the Constitution of the Philippines, and removes straits 

connecting these waters with the economic zone or high sea from the rights 

of foreign vessels to transit passage for international navigation;

7U.N. Office for Oceans Affairs and the Law of the Sea, Law of the Sea Bulletin, Special Issue 1, March 

1987, Annex II, p. 6, quoted in Sweeney, Oliver, Leech, THE INTERNATIONAL LEGAL SYSTEM, 193 (3RD ED. 1988).

126 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

However, concern about this problem may not be necessary because Article 

8(2) itself says that the new rule applies only to “areas which had not previously 

been considered as ‘internal waters.”’ The 1973 Constitution pre-dates the 1982 

Convention.

Bays.

The waters of a bay are considered internal waters of a coastal state. The 

rule on bays is found in Article 10 of the 1982 LOS: 

2. For the purposes of this Convention, a bay is a well- marked 

indentation whose penetration is in such proportion to the width of its 

mouth as to contain land-locked waters and constitute more than a mere 

curvature of the coast. An indentation shall not, however, be regarded as a 

bay unless its area is as large as, or larger than, that of the semi-circle whose 

diameter is a line drawn across the mouth of that indentation.

3. For the purpose of measurement, the area of an indentation is 

that lying between the low-water mark around the shore of the indentation 

and a line joining the low-water mark of its natural entrance points. Where, 

because of the presence of islands, an indentation has more than one mouth,

the semi-circle shall be drawn on a line as long as the sum total of the 

lengths of the lines across the different mouths. Islands within an 

indentation shall be included as if they were part of the water area of the 

indentation.

4. If the distance between the low-water marks of the natural 

entrance points of a bay does not exceed 24 nautical miles, a closing line 

may be drawn between these two low-water marks, and the waters enclosed 

thereby shall be considered as internal waters.

5. Where the distance between the low-water marks of the natural 

entrance points of a bay exceeds 24 nautical miles, a straight baseline of 24 

nautical miles shall be drawn within the bay in such a manner as to enclose 

the maximum area of water that is possible with a line of that length.

6. The foregoing provisions do not apply to so-called “historic” 

bays, or in any case where the system of straight baselines provided for in 

Article 7 is applied.

CHAPTER 8

TERRITORY: LAW OF THE SEA

127

Historic bays are bays which are treated by the coastal state as internal 

waters on the basis of historic rights acknowledged by other states. A listing of 

historic bays may be found in 4 Whitman, DIGEST OF INTERNATIONAL LAW 233-39 (1965).

Contiguous zone.

The contiguous zone is an area of water not exceeding 24 nautical miles 

from the baseline. It thus extends 12 nautical miles from the edge of the territorial 

sea. The coastal state exercises authority over that area to the extent necessary to 

prevent infringement of its customs, fiscal, immigration or sanitation authority 

over its territorial waters or territory and to punish such infringement. Article 33 (1 

and 2), 1982 LOS says:

1. In a zone contiguous to its territorial sea, described as the 

contiguous zone, the coastal State may exercise the control necessary to:

(a) prevent infringement of its customs, fiscal, immigration 

or sanitary laws and regulations within its territory or territorial sea;

(b) punish infringement of the above laws and regulations 

committed within its territory or territorial sea.

2. The contiguous zone may not extend beyond 24 nautical miles 

from the baselines from which the breadth of the territorial sea is measured.

It should be understood, however, that, according to the International Law 

Commission’s Commentary on the Draft, the power of control given to the littoral 

state does not change the nature of the waters. Beyond the territorial sea, the 

waters are high sea and are not subject to the sovereignty of the coastal state.

Exclusive economic zone or “patrimonial sea.”

The doctrine on the exclusive economic zone is a recent development. Prior 

to the acceptance of this doctrine, all waters beyond the contiguous zone were 

considered as high seas over which no state had control. The doctrine developed 

owing to the desire of coastal states for better conservation and management of 

coastal fisheries.

128 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The exclusive economic zone is an area extending not more than 200 

nautical miles beyond the baseline. The coastal state has rights over the economic 

resources of the sea, seabed and subsoil — but the right does not affect the right of 

navigation and overflight of other states. This is a compromise between those who 

wanted a 200-mile territorial sea and those who wanted to reduce the powers of 

coastal states.

The provisions on the exclusive economic zone are both a grant of rights to 

and an imposition of obligations on coastal states relative to the exploitation, 

management and preservation of the resources found within the zone.

Coastal states have two primary obligations. First, they must ensure through 

proper conservation and management measures that the living resources of the 

EEZ are not subjected to over-exploitation. This includes the duty to maintain and 

restore populations of harvested fisheries at levels which produce a “maximum 

sustainable yield.” Second, they must promote the objective of “optimum 

utilization” of the living resources. They therefore should determine the allowable 

catch of living resources. If the coastal state does not have the capacity to harvest 

the allowable catch, it must grant access to other states. The details on this matter 

are found in Articles 55 to 75.

The delimitation of the overlapping exclusive economic zone between 

adjacent states is determined by agreement.

The Continental (Archipelagic) Shelf.

The continental shelf, archipelagic or insular shelf for archipelagos, refers to 

(a) the seabed and subsoil of the submarine areas adjacent to the coastal state but 

outside the territorial sea, to a depth of two hundred meters or, beyond that limit, 

to where the depth allows exploitation, and (b) the seabed and subsoil of areas 

adjacent to islands. The coastal state has the right to explore and exploit its natural 

resources, to erect installations needed, and to erect a safety zone over its 

installations with a radius of 500 meters. The right does not affect the right of 

navigation of others. Moreover, the right does not extend to non-resource material 

in the shelf area such as wrecked ship and their cargoes.

mon heritage of mankind and may not be appropriated by any state or person.

Activities in the area are governed by Articles 135 tol53 of the 1982 Convention.

Islands.

Article 121. Regime of islands

1. An island is a naturally formed area of land, surrounded 

by water, which is above water at high tide.

2. Except as provided for in paragraph 3, the territorial sea, 

the contiguous zone and the continental shelf of an island are 

determined in accordance with the provisions of the Convention 

applicable to other land territory.

3. Rocks which cannot sustain human habitation or 

economic life of their own shall have no exclusive economic zone or 

continental shelf.

Islands can be very important because of the possibility of exploiting oil and 

gas resources around them. This explains the controversy over Spratleys. It is 

noteworthy that islands can have their own territorial sea, exclusive economic zone 

and continental shelf. However, rocks “which cannot sustain human habitation or 

economic life” only have a territorial sea. But there is no clear international law 

definition of “economic life” referred to in n. 3.

Artificial islands or installations are not “islands” in the sense of Article 121. 

However, coastal states may establish safety zones around artificial islands and 

prescribe safety measures around them. (Article 60[4] and [5])

The High Seas.

Article 1 of the Geneva Convention on the High Seas defines the high seas 

as “all parts of the sea that are not included in the territorial sea or in the internal 

waters of a State.”

The highs seas are subject to six freedoms: (1) freedom of navigation; (2) 

freedom of overflight; (3) freedom of fishing; (4) freedom to lay submarine cables 

and pipelines; (5) freedom to construct artificial islands and structures; and (6) 

freedom of scientific research.

130 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The first four of the above freedoms were mentioned in the 1958 

Convention of the High Seas and the last two were added by the 1982 LOS. But 

these two are subject to some restrictions.

The flag state has exclusive jurisdiction over its ships on the high seas to the 

extent not limited by agreement. By legal fiction, a ship is a floating part of the 

flag state. The law of the flag state is applied to it “on the pragmatic basis that 

there must be some law on shipboard, that it cannot change at every change of 

waters, and no experience shows a better rule than that of the state that owns it.”8

Freedom of overflight belongs to both civilian and military aircraft.

Freedom of fishing also includes the duty to cooperate in taking measures to 

ensure the conservation and management of the living resources of the high seas.

Article 86 of the 1982 LOS, on the six freedoms, says: “The provisions of 

this part apply to all parts of the sea that are not included in the exclusive 

economic zone, in the territorial sea or in the internal waters of a state, or in the 

archipelagic waters of an archipelagic state.” This, however, is not a definition of 

the scope of the area called “high seas.” As noted above, the contiguous zone is 

part of the high seas. What Article 86 does is to specify the areas that are not 

covered by all the six freedoms.

Hot Pursuit

Article 111 allows hot pursuit of a foreign vessel where there is good reason 

to believe that the ship has violated laws or regulations of a coastal state. The 

pursuit must commence when the foreign vessel is within the internal waters, the 

archipelagic waters, the territorial waters or the contiguous zone of the pursuing 

state. It may continue into the high seas if the pursuit has not been interrupted. If 

the foreign ship is in the contiguous zone, it may be pursued only for violations of 

the rights of the coastal state in the contiguous zone.

Mutatis mutandis, the right of hot pursuit shall also apply to violations of 

applicable laws and regulations of the coastal state in the

‘Lauritzen v. Larsen, 345 U.S. 571,585 (1953).

CHAPTER 8

TERRITORY: LAW OF THE SEA

131

exclusive economic zone or the continental shelf including the safety zones of the 

shelf.

Hot pursuit must stop as soon as the ship pursued enters the territorial 

waters if its own state or of a third state.

Hot pursuit may be carried out only by warships or military aircraft, or any 

other ship or aircraft properly marked for that purpose.

In the case of The I’m Alone (29 AJIL 326), although the pursuit was found 

to be legitimate, the sinking of the pursued vessel was found to be “not justified by 

anything in the Convention ... [nor] by any principle of international law.” The 

Commission ordered the United States to apologize to the Canadian government 

and to pay damages.

Settlement of Disputes.

Peaceful settlement of disputes is compulsory. Under Part XV of the 1982 

Convention States are required to settle peacefully disputes concerning the 

Convention. If a bilateral settlement fails, Article 285 requires submission of the 

dispute for compulsory settlement in one of the tribunals clothed with jurisdiction. 

The alternatives are the International Tribunal for the Law of the Sea, the ICJ, or 

an arbitral tribunal constituted under the Convention.

Chapter 9 JURISDICTION OF STATES

Jurisdiction means the authority to affect legal interests. Corresponding to 

the powers of government, jurisdiction can be: (^jurisdiction to prescribe norms of 

conduct (legislative jurisdiction), (2) jurisdiction to enforce the norms prescribed 

(executive jurisdiction), and (3) jurisdiction to adjudicate (judicial jurisdiction).

The scope of a state’s jurisdiction over a person, thing, or event depends on 

the interest of the state in affecting the subject in question. Where there are 

competing interests among various states, there may be a need to establish 

priorities on the basis of the quality and quantity of the linkages the various states 

have. For that matter, it is possible for more than one sovereignty to have 

jurisdiction over the same subject matter.

International law limits itself to criminal rather than civil jurisdiction. Civil 

jurisdiction is a subject for private international law or conflicts of law.

Writers have come up with five principles as follows:

1) the territoriality 

principle;

2) the nationality 

principle;

3) the protective principle;

4) the universality 

principle; and

5) the passive personality 

principle.

The first three are generally supported in customary law; the fourth finds 

application in special circumstances; but the fifth does not enjoy wide acceptance. 

Of co rse j risdiction ma also be acq ired thro gh treat

132

CHAPTER 9

JURISDICTION OF STATES

133

The Territoriality Principle.

The fundamental source of jurisdiction is sovereignty over territory. A state 

has absolute, but not necessarily exclusive, power to prescribe, adjudicate and 

enforce rules for conduct that occurs within its territory. For this reason, it is 

necessary that boundaries be determined. The Third Restatement summarizes the 

rules on boundaries where states are not islands but parts of a larger land mass 

thus:

(1) the boundary separating the land areas of two states

is determined by acts of the states expressing their consent to its

location.

(2) Unless a consent to a different rule has been expressed,

(a) when the boundary between two states is a navigable 

river, its location is the middle of the channel of navigation (Thalweg 

doctrine)',

(b) when the boundary between two states is a nonnavigable river or a lake, its location is the middle of the river or lake.

In this regard it is important to recall what was said in the Las Palmas case: 

to have jurisdiction, occupation is not enough; control must also be established.

The Philippines has no problem with surface land boundaries because we 

have no contiguous neighbors. However, because we are very close to other Asian 

states, knowing where our boundaries end may be necessary for purposes of 

determining our exclusive economic zone, treated earlier in Chapter 9.

Effects Doctrine

An aspect of the territoriality principle is the “effects doctrine A state also 

has jurisdiction over acts occurring outside its territory but having effects within it. 

This was enunciated in the Lotus case, an early case dealing with territorial 

jurisdiction.

The effects doctrine itself consists of two principles. First, there is the 

subjective territorial principle which says that a state has jurisdiction to prosecute 

and punish for crime commenced within the state but completed or consummated 

abroad. The second is the objective territorial principle which says that a state has 

jurisdiction to prosecute and

134 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

punish for crime commenced without the state but consummated within its 

territory. See the Trail Smelter Arbitration.

THE LOTUS CASE FRANCE V. TURKEY PCU (1927)

Background

On August 2, 1926, just before midnight, a French mail 

steamer Lotus, on the way to Constantinople, collided with the 

Turkish cutter Boz-Kourt on the high seas. The Boz-Kourt sank with 

the loss of eight sailors, all Turkish nationals. The Lotus subsequently 

arrived in Constantinople at which point Turkish authorities arrested 

Lieutenant Demons, the French officer in charge of the Lotus at the 

time of the collision, and Hassan Bey, the captain of the Boz-Kourt. 

Both were charged with manslaughter.

Lieutenant Demons argued that the Turkish Courts had no 

jurisdiction. This argument was rejected and he was sentenced to 

eighty days imprisonment and a fine of twenty-two pounds. Hassan 

Bey received a slightly heavier sentence.

The French Government objected to the actions of the Turkish 

Court. The French and the Turks agreed to submit the dispute to the 

Permanent Court of International Justice (the precursor to the ICJ).

In submitting the dispute to the PCIJ, an agreement was drawn 

up according to which the Court had to decide:

1. Has Turkey by instituting criminal proceedings in pursuance of Turkish law against M. Demons, officer of the watch on 

board the Lotus at the time of the collision, in consequence of the loss 

of the Boz-Kourt having involved the death of eight Turkish sailors 

and passengers violated international law?

Judgment:

The Court, having to consider whether there are any rules of 

international law which may have been violated by the prosecution in 

pursuance of Turkish law of Lieutenant Demons, is confronted in the 

first place by a question of principle which . . . has proved to be a 

fundamental one. The French Government contends that the Turkish

Courts, in order to have jurisdiction, should be able to point to some 

title to jurisdiction recognized by international law in favor of 

Turkey. On the other hand, the Turkish Government

CHAPTER 9

JURISDICTION OF STATES

takes the view that Turkey has jurisdiction whenever such jurisdiction 

does not come into conflict with a principle of international law.

Though it is true that in all systems of law, the principle of the 

territorial character of criminal law is fundamental, it is equally true 

that all or nearly all these systems of law extend their action to 

offenses committed outside the territory of the State which adopts 

them, and they do so in ways which vary from State to State. The 

territoriality of criminal law, therefore, is not an absolute principle of 

international law and by no means coincides with territorial sovereignty.

The Court therefore must ... ascertain whether or not there 

exists a rule of international law limiting the freedom of States to 

extend the criminal jurisdiction of their courts to a situation uniting 

the circumstances of the present case.

... [T]he characteristic features of the situation of fact are as 

follows there has been a collision on the high seas between two 

vessels flying different flags, on one of which was one of the persons 

alleged to be guilty of the offense, whilst the victims were on board 

the other.

It is certainly true that — apart from special cases which are 

defined by international law — vessels on the high seas are subject to 

no authority except that of the State whose flag they fly. In virtue of 

the principle of the freedom of the seas, that is to say, the absence of 

any territorial sovereignty upon the high seas, no State may exercise 

any kind of jurisdiction over foreign vessels upon them....

But it by no means follows that a State can never in its own 

territory exercise jurisdiction over acts which have occurred on board 

a foreign ship on the high seas. A corollary of the principle of the 

freedom of the seas is that a ship on the high seas is assimilated to the 

territory of the State the flag of which it flies, for, just as in its own 

territory, that State exercises its authority upon it, and no other State 

may do so. All that can be said is that by virtue of the principle of the 

freedom of the seas, a ship is placed in the same position as national 

territory, but there is nothing to support the claim according to which 

the rights of the State under whose flag the vessel sails may go farther 

than the rights which it exercises within its territory properly socalled. It follows that what occurs on board a

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

vessel upon the high seas must be regarded as if it occurred on the 

territory of the State whose flag the ship flies. If, therefore, a guilty 

act committed on the high seas produces its effects on a vessel flying 

another flag or in foreign territory, the same principles must be 

applied as if the territories of two different States were concerned, and 

the conclusion must therefore be drawn that there is no rule of 

international law prohibiting the State to which the ship on which the 

effects of the offense have taken place belongs, from regarding the 

offense as having been committed in its territory and prosecuting, 

accordingly, the delinquent.

This conclusion could only be overcome if it were shown that 

there was a rule of customary international law which, going further 

than the principle stated above, established the exclusive jurisdiction 

of the State whose flag was flown. The French Government has 

endeavored to prove the existence of such a rule, having recourse for 

this purpose to the teachings of publicists, to decisions of municipal 

and international tribunals, and especially to conventions which, 

whilst creating exceptions to the principle of the freedom of the seas 

by permitting the war and police vessels of a State to exercise a more 

or less extensive control over the merchant vessels of another State, 

reserve jurisdiction to the courts of the country as is flown by the 

vessel proceeded against.

In the Court’s opinion, the existence of such a rule has not been 

conclusively proved.

In the first place, as regards teachings of publicists, and apart

from the question as to what their value may be from the point of 

view of establishing the existence of a rule of customary law, it is no 

doubt true that all or nearly all writers teach that ships on the high 

seas are subject exclusively to the jurisdiction of the State whose flag 

they fly. But the important point is the significance attached by them 

to this principle; now it does not appear that in general, writers 

bestow upon this principle a scope differing from or wider than that 

explained above and which is equivalent to saying that the jurisdiction 

of a State over vessels on the high seas is the same in extent as its 

jurisdiction in its own territory. On the other hand, there is no lack of 

writers who, upon a close study of the special question whether a 

State can prosecute for offenses committed on board a foreign ship on 

the high seas, definitely come to the conclusion that such offenses 

must be regarded as if they had been committed in the territory of the 

State whose flag the ship flies, and that consequently, the general 

rules of each legal system in regard to offenses committed abroad are 

applicable.

CHAPTER 9

JURISDICTION OF STATES

137

In regard to precedents, it should first be observed that, leaving 

aside the collision cases ... none of them relates to offenses affecting 

two ships flying the flags of different countries, and consequently 

they are not of much importance in the case before the Court. ...

On the other hand, there is no lack of cases in which a State has 

claimed a right to prosecute for an offense, committed on board a 

foreign vessel, which it regarded as punishable under its legislation....

The conclusion at which the Court has therefore arrived is that 

there is no rule of international law in regard to collision cases to the 

effect that criminal proceedings are exclusively within the jurisdiction 

of the State whose flag is flown....

The offense for which Lieutenant Demons appears to have been 

prosecuted was an act of negligence or imprudence — having its 

origin on board the Lotus, whilst its effects made themselves felt on 

board the Boz-Kourt. These two elements are, legally, entirely 

inseparable so much so that their separation renders the offense nonexistent. Neither the exclusive jurisdiction of either State, nor the

limitations of the jurisdiction of each to the occurrences which took

place on the respective ships would appear calculated to satisfy the 

requirements of justice and effectively to protect the interests of the 

two States. It is only natural that each should be able to exercise 

jurisdiction and to do so in respect of the incident as a whole. It is 

therefore a case of concurrent jurisdiction....

Jurisdiction over foreign vessels in Philippine Territory

Regarding crimes committed on foreign vessels within Philippine territory, 

the Supreme Court had this to say:

There are two fundamental rules on this particular matter in connection with 

international law; to wit, the French rule, according to which crimes committed 

aboard a foreign merchant vessel should not be prosecuted in the courts of the 

country within whose territorial jurisdiction they were committed unless their 

commission affects the peace and security of the territory; and the English rule, 

based on the territorial principle and followed in the United States, according to 

which, crimes perpetrated under such circumstances are in general triable in the 

courts of the country within whose territory they were committed. Of these

138 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

two rules, it is the last one that obtains in this jurisdiction, because at present the 

theories and jurisprudence prevailing in the United States on the matter are 

authority in the Philippines which is now a territory of the United States. 

(Syllabus, People v. Wong Cheng, 46 Phil 729 [1922])

TRAIL SMELTER ARBITRATION US v. Canada (1938-41)

(Abridged)

The President of the United States of America, and His Majesty 

the King of Great Britain, Ireland and the British dominions beyond 

the Seas, Emperor of India, in respect of the Dominion of Canada.

Considering that the Government of the United States has 

complained to the Government of Canada that fumes discharged from 

the smelter of the consolidated Mining and Smelting company at 

Trail, British Columbia, have been causing damage in the State of 

Washington, and

Recognizing the desirability and necessity of effecting a permanent settlement,

Have decided to conclude a convention for the purposes 

aforesaid...

The Governments of the United States and of Canada, hereinafter referred to as “the Governments,” mutually agree to constitute 

a tribunal... for the purpose of deciding the questions referred to it...

The Tribunal shall finally decide the questions, hereinafter 

referred to as “the Questions,” set forth hereunder, namely:

1. Whether damage caused by the Trail Smelter in 

the State of Washington has occurred since the first day of 

January, 1932, and, if so, what indemnity should be paid 

therefor?

2. In the event of the answer to the first part of the 

preceding Question being in the affirmative, whether the Trail 

Smelter should be required to refrain from causing damage in

the State of Washington in the future and, if so, to what extent?

3. I

n the light of the answer to the preceding Question, what 

measures or regime, if any, should be adopted or maintained by 

the Trail Smelter?

CHAPTER 9

JURISDICTION OF STATES

4. What indemnity or compensation, if any, should

be paid on account of any decision or decisions rendered by

the Tribunal pursuant to the next two preceding Questions?

The controversy is between two governments involving damage 

occurring in the territory of one of them (the United States of 

America) and alleged to be due to an agency situated in the territory 

of the other (the Dominion of Canada), for which damage the latter 

has assumed by the Convention an international responsibility....

In conclusion, the Tribunal answers Question 1 in Article III, as 

follows: Damage caused by the Trail Smelter in the State of 

Washington has occurred since the first day of January, 1932, and up 

to October 1,1937, and the indemnity to be paid therefor is seventyeight thousand dollars ($78,000), and is to be complete and final 

indemnity and compensation for all damage which occurred between 

such dates. ...

As Professor Eagleton puts it Responsibility of States in 

International Law, 1928, p. 80: “A State owes at all times a duty to 

protect other States against injurious acts by individuals from within 

its jurisdiction.” A great number of such general pronouncements by 

leading authorities concerning the duty of a State to respect other 

States and their territory have been presented to the Tribunal.... [T]his 

principle, as such, has not been questioned by Canada. But the real 

difficulty often arises rather when it comes to determine what... is

deemed to constitute an injurious act.

Considering the circumstances of the case, the Tribunal holds 

that the Dominion of Canada is responsible in international law for 

the conduct of the Trail Smelter.... It is, therefore, the duty of the 

government of the Dominion of Canada to see to it that this conduct 

should be in conformity with the obligation of the Dominion under 

international law as herein determined.

The Tribunal, therefore, answers question No. 2 as follows:

(2) so long as the present conditions in the Columbia River Valley 

prevail, the Trail Smelter shall be required to refrain from causing any 

damage through fumes in the State of Washington;...

140 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The Nationality Principle.

The nationality principle says that every state has jurisdiction over its 

nationals even when those nationals are outside the state. Blackmer v. United 

States, infra, is illustrative of this principle.

BLACKMER V. UNITED STATES 284 U.S. 421 (1932)

Mr. Chief Justice HUGHES delivered the opinion of the Court.

The petitioner, Harry M. Blackmer, a citizen of the United 

States resident in Paris, France, was adjudged guilty of contempt of 

the Supreme Court of the District of Columbia for failure to respond 

to subpoenas served upon him in France and requiring him to appear 

as a witness on behalf of the United States at a criminal trial in that 

court. Two subpoenas were issued, for appearances at different times, 

and there was a separate proceeding with respect to each. The two 

cases were heard together, and a fine of $30,000 with costs was 

imposed in each case, to be satisfied out of the property of the 

petitioner which had been seized by order of the court. ...

The subpoenas were issued and served, and the proceedings to punish 

for contempt were taken, under the provisions of the Act of July 3, 

1926, c. 762, 44 Stat. 835, U.S.C., tit. 28, 711-718 (28 USCA 711-

718).

The statute provided that [284 U.S. 421,434] whenever the 

attendance at the trial of a criminal action of a witness abroad, who is 

‘a citizen of the United States or domiciled therein,’ is desired by the 

Attorney General, or any assistant or district attorney acting under

him, the judge of the court in which the action is pending may order a 

subpoena to issue, to be addressed to a consul of the United States 

and to be served by him personally [284 U.S. 421,

435] upon the witness with a tender of traveling expenses. Sections 2, 

3 of the act (28 USCA 712,713).

This statute and the proceedings against the petitioner are assailed as being repugnant to the Constitution of the United States.

First. The principal objections to the statute are that it violates the due process 

clause of the Fifth Amendment. These contentions are:

(1) That the ‘Congress has no power to authorize United States 

consuls to serve process except as permitted by treaty’; (2) that the

act does not provide ‘a valid method of acquiring judicial jurisdic- 

CHAPTER 9

JURISDICTION OF STATES

tion to render personal judgment against defendant and judgment 

against his property’; (3) that the act ‘does not require actual or any 

other notice to defendant of the offense or of the Government’s claim

against his property’; (4) that the provisions ‘for hearing and 

judgment in the entire absence of the accused and without his consent’ are invalid; and (5) that the act is ‘arbitrary, capricious and 

unreasonable.’

While it appears that the petitioner removed his residence to 

France in the year 1924, it is undisputed that he was, and continued to 

be, a citizen of the United States. He continued to owe allegiance to 

the United States. By virtue of the obligations of citizenship, the 

United States retained its authority over him, and he was bound by its 

laws made applicable to him in a foreign country. Thus, although 

resident abroad, the petitioner remained subject to the taxing power of 

the United States. Cook v. Tait, 265 US. 47, 54, 56 S., 44 S. Ct. 444.

For disobedience to its laws through conduct abroad, he was subject 

to punishment in the courts of the United States. United States v. 

Bowman [284 US. 421, 437], 260 US. 94,102, 43 S. Ct. 39.

With respect to such an exercise of authority, there is no 

question of international law, but solely of the purport of the 

municipal law which establishes the duties of the citizen in relation to 

his own government. While the legislation of the Congress, unless the 

contrary intent appears, is construed to apply only within the 

territorial jurisdiction of the United States, the question of its 

application, so far as citizens of the United States in foreign countries 

are concerned, is one of construction, not of legislative power. 

American Banana Co. v. United Fruit Co., 213 US. 347, 357, 29 S. Ct. 

511, 16 Ann. Cas. 1047; United States v. Bowman, supra; Robertson v. 

Labor Board, 268 US. 619,622,45 S. Ct. 621. Nor can it be doubted 

that the United States possesses the power inherent in sovereignty to 

require the return to this country of a citizen, resident elsewhere, 

whenever the public interest requires it, and to penalize him in case of 

refusal. Compare Bartue and the Duchess of Suffolk’s Case, 2 Dyer’s 

Rep. 176b, 73 Eng. Rep. 388; Knowles v. Luce, Moore 109, 72 Eng. 

Rep. 473.4. What in England was the prerogative of the sovereign in 

this respect pertains under our constitutional system to the national 

authority which may be exercised by the Congress by virtue of the 

legislative power to prescribe the duties of the citizens of the United 

States.

It is also beyond controversy that one of the duties which the 

citizen owes to his government is to support the administration of

142 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

justice by attending its courts and giving his testimony whenever he is 

properly summoned. Blair v. United States, 250 US. 273,

281, 39 S. St. Ct. 468. And the Congress may provide for the performance of this duty and prescribe penalties for disobedience. ...

Each state has the right to decide who are its nationals using either the 

principle ofjus sanguinis or jus soli or naturalization laws. However, for a state to 

claim a person as a national, the state must have reasonable connection or an 

“effective link” with that person. The consent of the individual alone is not enough 

for him to be recognized by other states as a national of the state to which he 

claims to belong. The Nottebohm case (Liechtenstein v. Guatemala), infra, is 

illustrative.

Effective Nationality Link

The doctrine on effective nationality link is used to determine which of two 

states of which a person is a national will be recognized as having the right to give 

diplomatic protection to the holder of dual nationality. The doctrine is found in the 

Nottebohm case.

THE NOTTEBOHM CASE 

Liechtenstein v. Guatemala

I. CJ. 

1955 

(Abridged)

Background

Nottebohm was a German national by birth. In 1905, at the age 

of 24, he moved to Guatemala, where he maintained a residence and a 

business enterprise. On several occasions, he made business trips to 

Germany. Between 1931 and 1939, he visited a brother in 

Liechtenstein on several occasions. The rest of his relatives and 

friends lived in Germany or Guatemala. In October 1939 (shortly 

after the outbreak of World War II), he applied for citizenship by 

naturalization in Liechtenstein.

Nottebohm asked for a waiver of the residence requirement, 

paid his naturalization fees, and gave a deposit for the payment of 

taxes. By the end of October 1939, he was granted citizenship and 

received a Liechtenstein passport. On December 1,1939, he received 

a visa from the Guatemalan Consul in Zurich. Nottebohm then 

returned to Guatemala.

Several months before declaring war on Germany, the United States 

blacklisted Nottebohm and froze his U.S. assets. Like

CHAPTER 9

JURISDICTION OF STATES

143

the United States, Guatemala entered World War II against Germany 

in December 1941. In 1943, Guatemala arrested Nottebohm as a 

dangerous enemy alien and deported him to the United States, where 

he was interned until 1946. He then returned to Liechtenstein, after 

Guatemala refused his application for readmission. By 1949, 

Guatemala had confiscated his property on the grounds that he was an 

enemy alien.

In 1951, Liechtenstein brought this action against Guatemala, 

asking the Court to declare that: “The Government of Guatemala in 

arresting, detaining, expelling and refusing to readmit Mr. Nottebohm 

and in seizing and retaining his property without compensation acted 

in breach of their obligations under international law and 

consequently in a manner requiring the payment of reparation.” For 

its part, Guatemala asked the Court to declare the claim inadmissible 

on grounds of the nationality of the claimant.

Decision

Guatemala has referred to a well-established principle of international law,... 

that ‘it is the bond of nationality between the State and the individual which alone 

confers upon the State the right of diplomatic protection’....

Liechtenstein considers itself to be acting in conformity with this principle 

and contends that Nottebohm is its national by virtue of the naturalization 

conferred upon him. ... Guatemala, on the other hand, requests] the Court ‘to 

declare that the claim of the Principality of Liechtenstein is inadmissible’, and 

set[s] forth a number of grounds relating to the nationality of Liechtenstein granted 

to Nottebohm by naturalization. Thus, the real issue before the Court is the 

admissibility of the claim of Liechtenstein in respect of Nottebohm.

In order to decide upon the admissibility of the application, the court must 

ascertain whether the nationality conferred on Nottebohm by Liechtenstein ... 

bestows upon Liechtenstein a sufficient title to the exercise of protection in respect 

of Nottebohm as against Guatemala and therefore entitles it to seise the Court of a 

claim relating to him.

Liechtenstein has argued that Guatemala formerly recognized the 

naturalization which it now challenges and cannot therefore be heard to put 

forward a contention which is inconsistent with its former attitude. ... Reliance has 

been placed on the fact that... the Consul-General of

144 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Guatemala in Zurich entered a visa in the Liechtenstein passport of Mr. 

Nottebohm for his return to Guatemala; that on January 29,1940 Nottebohm 

informed the Ministry of External Affairs in Guatemala that he had adopted the 

nationality of Liechtenstein and therefore requested that the entry relating to him 

in the Register of Aliens should be altered accordingly, a request which was 

granted on January 31; that on February 9, 1940 a similar amendment was made 

to his identity document, and lastly that a certificate to the same effect was issued 

to him by the civil registry of Guatemala on July 1,1940.

The acts of the Guatemalan authorities proceeded on the basis of the 

statements made to them by the person concerned. ... All of these acts have 

reference to the control of aliens in Guatemala and not to the exercise of 

diplomatic protection. When Nottebohm thus presented himself before the

Guatemalan authorities, the latter had before them a private individual: there did 

not thus come into being any relationship between governments. There was 

nothing in all this to show that Guatemala then recognized that the naturalization 

conferred upon Nottebohm gave Liechtenstein any title to the exercise of 

protection.

In a letter of the Swiss consul of December 15, 1944, to the Minister of 

External Affairs, reference is made to the entry on the Black Lists of “Frederick

Nottebohm, a national of Liechtenstein.” ... Guatemala, in its reply ... expressly 

stated that it could not “recognise that Mr. Nottebohm, a German subject 

habitually resident in Guatemala, has acquired the nationality of Liechtenstein 

without changing his habitual residence.” ... There is here an express denial by 

Guatemala of Nottebohm’s Liechtenstein nationality....

There is nothing here to show that before the institution of proceedings 

Guatemala had recognised Liechtenstein’s title to exercise protection in favor of 

Nottebohm and that it is thus precluded from denying such a title. ... Since no 

proof has been adduced that Guatemala has recognized the title to the exercise of 

protection relied upon by Liechtenstein as being derived from the naturalization 

which it granted to Nottebohm, the Court must consider whether such an act of 

granting nationality by Liechtenstein directly entails an obligation on the part of 

Guatemala to recognize its effect, namely, Liechtenstein’s right to exercise its 

protection....

It is for Liechtenstein, as it is for every sovereign State, to settle by its own 

legislation the rules relating to the acquisition of its

CHAPTER 9

JURISDICTION OF STATES

145

nationality, and to confer that nationality by naturalization granted by its own 

organs in accordance with that legislation. It is not necessary to determine whether 

international law imposes any limitations on its freedom of decision in this 

domain. Furthermore, nationality has its most immediate, its most far-reaching 

and, for most people, its only effects within the legal system of the State 

conferring it. Nationality serves above all to determine that the person upon whom 

it is conferred enjoys the rights and is bound by the obligations which the law of 

the State in question grants to or imposes on its nationals. This is implied in the 

wider concept that nationality is within the domestic jurisdiction of the State.

But the issue which the Court must decide is not one which pertains to the 

legal system of Liechtenstein. It does not depend on the law or on the decision of 

Liechtenstein whether that State is entitled to exercise its protection, in the case 

under consideration. To exercise protection, to apply to the Court is to place 

oneself on the plane of international law. It is international law which determines 

whether a State is entitled to exercise protection and to seise the Court.

The naturalization of Nottebohm was an act performed by Liechtenstein in 

the exercise of its domestic jurisdiction. The question to be decided is whether that 

act has the international effect here under consideration. International practice 

provides many examples of acts performed by States in the exercise of their 

domestic jurisdiction which do not necessarily or automatically have international 

effect, which are not necessarily and automatically binding on other States or 

which are binding on them only subject to certain conditions....

When one State has conferred its nationality upon an individual and another 

State has conferred its own nationality on the same person, it may occur that each 

of these States, considering itself to have acted in the exercise of its domestic 

jurisdiction, adheres to its own view and bases itself thereon in so far as its own 

actions are concerned. In so doing, each State remains within the limits of its 

domestic jurisdiction.

This situation may arise on the international plane and fall to be considered 

by international arbitrators or by the courts of a third State. If the arbitrators or the 

courts of such a State should confine themselves to the view that nationality is 

exclusively within the domestic jurisdiction of the State, it would be necessary for 

them to find that they were

146 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

confronted by two contradictory assertions made by two sovereign States, 

assertions which they would consequently have to regard as of equal weight, 

which would oblige them to allow the contradiction to subsist and thus fail to 

resolve the conflict submitted to them....

International arbitrators have decided ... numerous cases of dual nationality, 

where the question arose with regard to the exercise of protection. They have 

given their preference to the real and effective nationality, that which accorded 

with the facts, that based on stronger factual ties between the person concerned 

and one of the States whose nationality is involved. Different factors are taken into 

consideration, and their importance will vary from one case to the next: the 

habitual residence of the individual concerned is an important factor, but there are 

other factors such as the centre of his interests, his family ties, his participation in 

public life, attachment shown by him for a given country and inculcated in his 

children, etc.

Similarly, the courts of third States, when they have before them an

individual whom two other States hold to be their national, seek to resolve the 

conflict by having recourse to international criteria and their prevailing tendency is 

to prefer the real and effective nationality.

The same tendency prevails in the writings of publicists and in practice. 

This notion is inherent in the provisions of Article 3, paragraph

2, of the Statute of the Court. National laws reflect this tendency when, inter alia,

they make naturalization dependent on conditions indicating the existence of a 

link, which may vary in their purpose or in their nature but which are essentially 

concerned with this idea. The Liechtenstein Law of January 4th, 1934, is a good 

example.

The practice of certain States which refrain from exercising protection in 

favor of a naturalized person when the latter has in fact, by his prolonged absence, 

severed his links with what is no longer for him anything but his nominal country, 

manifests the view of these States that, in order to be capable of being invoked 

against another State, nationality must correspond with the factual situation. A 

similar view is manifested in the relevant provisions of the bilateral nationality 

treaties concluded between the United States of America and other States since 

1868, such as those sometimes referred to as the Bancroft Treaties, and in the PanAmerican Convention, signed at Rio de Janeiro on August 13th, 1906, on the 

status of naturalized citizens who resume residence in their country of origin.

CHAPTER 9

JURISDICTION OF STATES

147

The character thus recognized on the international level as pertaining to 

nationality is in no way inconsistent with the fact that international law leaves it to 

each State to lay down the rules governing the grant of its own nationality. The 

reason for this is that the diversity of demographic conditions has thus far made it 

impossible for any general agreement to be reached on the rules relating to 

nationality, although the latter by its very nature affects international relations. It 

has been considered that the best way of making such rules accord with the varying demographic conditions in different countries is to leave the fixing of such 

rules to the competence of each State. On the other hand, a State cannot claim that 

the rules it has thus laid down are entitled to recognition by another State unless it 

has acted in conformity with this general aim of making the legal bond of 

nationality accord with the individual’s genuine connection with the State which 

assumes the defense of its citizens by means of protection as against other States.

The requirement that such a concordance must exist is to be found in the 

studies carried on in the course of the last thirty years upon the initiative and under 

the auspices of the League of Nations and the United Nations. It explains the 

provision which the Conference for the Codification of International Law, held at 

The Hague in 1930, inserted in Article I of the Convention relating to the Conflict 

of Nationality Laws, laying down that the law enacted by a State for the purpose of 

determining who are its nationals “shall be recognized by other States in so far as 

it is consistent with ... international custom, and the principles of law generally 

recognized with regard to nationality.” In the same spirit, Article 5 of the 

Convention refers to criteria of the individual’s genuine connections for the 

purpose of resolving questions of dual nationality which arise in third States.

According to the practice of States, to arbitral and judicial decisions and to 

the opinions of writers, nationality is a legal bond having as its basis a social fact 

of attachment, a genuine connection of existence, interests and sentiments, 

together with the existence of reciprocal rights and duties. It may be said to 

constitute the juridical expression of the fact that the individual upon whom it is 

conferred, either directly by the law or as the result of an act of the authorities, is 

in fact more closely connected with the population of the State conferring 

nationality than with that of any other State. Conferred by a State, it only entitles 

that State to exercise protection vis-d-vis another State, if it constitutes a

148 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

translation into juridical terms of the individual’s connection with the State which 

has made him its national.

Diplomatic protection and protection by means of international judicial 

proceedings constitute measures for the defense of the rights of the State. As the 

Permanent Court of International Justice has said and repeated, “by taking up the 

case of one of its subjects and by resorting to diplomatic action or international 

judicial proceedings on his behalf, a State is in reality asserting its own rights —

its right to ensure in the person of its subjects respect for the rules of international 

law.”

Since this is the character which nationality must present when it is invoked 

to furnish the State which has granted it with a title to the exercise of protection 

and to the institution of international judicial proceedings, the Court must ascertain 

whether the nationality granted to Nottebohm by means of naturalization is of this 

character or, in other words, whether the factual connection between Nottebohm 

and Liechtenstein in the period preceding, contemporaneous with and following 

his naturalization appears to be sufficiently close, so preponderant in relation to 

any connection which may have existed between him and any other State, that it is 

possible to regard the nationality conferred upon him as real and effective, as the 

exact juridical expression of a social fact of a connection which existed previously 

or came into existence thereafter.

Naturalization is not a matter to be taken lightly. To seek and to obtain it is 

not something that happens frequently in the life of a human being. It involves his 

breaking of a bond of allegiance and his establishment of a new bond of 

allegiance. It may have far-reaching consequences and involve profound changes 

in the destiny of the individual who obtains it. It concerns him personally, and to 

consider it only from the point of view of its repercussions with regard to his 

property would be to misunderstand its profound significance. In order to appraise 

its international effect, it is impossible to disregard the circumstances in which it 

was conferred, the serious character which attaches to it, the real and effective, and 

not merely the verbal preference of the individual seeking it for the country which 

grants it to him.

At the time of his naturalization, does Nottebohm appear to have been more 

closely attached by his tradition, his establishment, his interests, his activities, his 

family ties, his intentions for the near future to Liechtenstein than of any other 

State? ...

CHAPTER 9

JURISDICTION OF STATES

The essential facts are as follows:

At the date when he applied for naturalization Nottebohm had 

been a German national from the time of his birth. He had always 

retained his connections with members of his family who had 

remained in Germany and he had always had business connections 

with that country. His country had been at war for more than a month, 

and there is nothing to indicate that the application for naturalization 

then made by Nottebohm was motivated by any desire to dissociate 

himself from the Government of his country.

He had been settled in Guatemala for 34 years. He had carried 

on his activities there. It was the main seat of his interests. He 

returned there shortly after his naturalization, and it remained the 

center of his interests and of his business activities. He stayed there 

until his removal as a result of war measures in 1943. He 

subsequently attempted to return there, and he now complains of 

Guatemala’s refusal to admit him. There, too, were several members 

of his family who sought to safeguard his interests.

In contrast, his actual connections with Liechtenstein were 

extremely tenuous. No settled abode, no prolonged residence in that 

country at the time of his application for naturalization; the 

application indicates that he was paying a visit there and confirms the 

transient character of this visit by its request that the naturalization 

proceedings should be initiated and concluded without delay. No 

intention of settling there was shown at that time or realized in the 

ensuing weeks, months or years — on the contrary, he returned to 

Guatemala very shortly after his naturalization and showed every 

intention of remaining there. If Nottebohm went to Liechtenstein in 

1946, this was because of the refusal of Guatemala to admit him. No 

indication is given of the grounds warranting the waiver of the 

condition of residence, required by the 1934 Nationality Law, which 

waiver was implicitly granted to him. There is no allegation of any 

economic interests or of any activities exercised or to be exercised in 

Liechtenstein, and no manifestation of any intention whatsoever to 

transfer all or some of his interests and business activities to 

Liechtenstein. It is unnecessary in this connection to attribute much

importance to the promise to pay the taxes levied at the time of his 

naturalization. The only links to be discovered between the 

Principality and Nottebohm are the short sojourns already referred to

and the presence in Vaduz of one of his brothers: but his brother’s 

presence is referred to in his application for naturalization only as a 

reference to his good

150 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

conduct. Furthermore, other members of his family have asserted 

Nottebohm’s desire to spend his old age in Guatemala.

These facts clearly establish, on the one hand, the absence of 

any bond of attachment between Nottebohm and Liechtenstein and, 

on the other hand, the existence of a long-standing and close 

connection between him and Guatemala, a link which his naturalization in no way weakened. That naturalization was not based on any 

real prior connection with Liechtenstein, nor did it in any way alter 

the manner of life of the person upon whom it was conferred in 

exceptional circumstances of speed and accommodation. In both 

respects, it was lacking in the genuineness requisite in an act of such 

importance, if it is to be entitled to be respected by a State in the 

position of Guatemala. It was granted without regard to the concept 

of nationality adopted in international relations.

Naturalization was asked for not so much for the purpose of 

obtaining a legal recognition of Nottebohm’s membership in fact in 

the population of Liechtenstein, as it was to enable him to substitute 

for his status as a national of a belligerent State that of a national of a 

neutral State, with the sole aim of thus coming within the protection 

of Liechtenstein but not of becoming wedded to its traditions, its 

interests, its way of life or of assuming the obligations — other than 

fiscal obligations — and exercising the rights pertaining to the status 

thus acquired.

Guatemala is under no obligation to recognize a nationality 

granted in such circumstances. Liechtenstein consequently is not 

entitled to extend its protection to Nottebohm vis-a-vis Guatemala 

and its claim must, for this reason, be held to be inadmissible.

The Court is not therefore called upon to deal with the other 

pleas in bar put forward by Guatemala or the conclusions of the 

Parties other than those on which it is adjudicating in accordance with 

the reasons indicated above.

For these reasons, the Court, by eleven votes to three, holds 

that the claim submitted by the Government of the Principality of 

Liechtenstein is inadmissible.

As to corporations, a state has jurisdiction over corporations organized 

under its laws. Many states assert jurisdiction over corporations whose principal 

place of business or registered office is located in their territories. States have also 

sought to regulate corporations organized or having their principal place of 

business abroad when these corpora

CHAPTER 9

JURISDICTION OF STATES

151

tions are owned or controlled by nationals. This last is controversial. More 

controversial still are multi-national corporations which register various addresses 

for different purposes. Thus, for instance, executive offices, sales operations, 

manufacturing and distribution facilities may each be located in different localities. 

These problems, however, are more properly under the domain of conflict of laws.

For maritime vessels, a state has jurisdiction over vessels flying its flag. 

(See Lotus case, supra.) Each state determines requirements for registration. But 

flags of convenience might be challenged on the ground of lack of sufficient link. 

The same principle is generally applicable to aircraft and spacecraft.

Stateless persons

Stateless persons are those who do not have a nationality. They are either de 

jure or de facto stateless. De jure stateless persons are those who have lost their 

nationality, if they had one, and have not acquired a new one. De facto stateless 

persons are those who have a nationality but to whom protection is denied by their 

state when out of the state. This is the situation of many refugees.

Since they do not enjoy protection by any state, how are they protected

against violations of their human rights such as by deportation to parts unknown? 

The following case offers an answer:

MEJOFF V. DIRECTOR OF PRISONS

90 Phil. 70 (1951)

TUASON, J.:

This is a second petition for habeas corpus by Boris Mejoff, 

the first having been denied in a decision of this Court of July 30,

1949. The history of the petitioner’s detention was thus briefly set 

forth in that decision, written by Mr. Justice Bengzon:

“The petitioner Boris Mejoff is an alien of Russian descent who 

was brought to this country from Shanghai as a secret operative by the 

Japanese forces during the latter’s regime in these Islands. Upon 

liberation, he was arrested as a Japanese spy, by U.S. Army Counter 

Intelligence Corps. Later, he was handed to the Commonwealth 

Government for disposition in accordance with Commonwealth Act 

No. 682. Thereafter, the People’s Court

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

ordered his release. But the Deportation Board taking his case up, 

found that having no travel documents Mejoff was illegally in this 

country, and consequently referred the matter to the immigration 

authorities. After the corresponding investigation, the Board of 

Commissioners of Immigration on April 5, 1948, declared that 

Mejoff had entered the Philippines illegally in 1944, without 

inspection and admission by the immigration officials at a 

designation port of entry and, therefore, it ordered that he be deported

on the first available transportation to Russia. The petitioner was then 

under custody, he having been arrested on March 18, 1948. In May 

1948, he was transferred to the Cebu Provincial Jail together with 

three other Russians to await the arrival of some Russian vessels. In 

July and August of that year, two boats of Russian nationality called 

at the Cebu Port. But their masters refused to take petitioner and his 

companions alleging lack of authority to do so. In October 1948, after 

repeated failures to ship this deportee abroad, the authorities removed him to Bilibid Prison at Muntinglupa where he has been 

confined up to the present time, inasmuch as the Commissioner of 

Immigration believes it is for the best interests of the country to keep 

him under detention while arrangements for his departure are being 

made.”

The Court held the petitioner’s detention temporary and said 

that “temporary detention is a necessary step in the process of 

exclusion or expulsion of undersirable aliens and that pending 

arrangements for his deportation, the Government has the right to 

hold the undersirable alien under confinement for a reasonable length 

of time.” It took note of the fact, manifested by the Solicitor 

General’s representative in the course of the oral argument, that “this 

Government desires to expel the alien, and does not relish keeping 

him at the people’s expense . . . making efforts to carry out the decree 

of exclusion by the highest officer of the land.” No period was fixed 

within which the immigration authorities should carry out the 

contemplated deportation beyond the statement that “The meaning of 

‘reasonable time’ depends upon the circumstances, specially the 

difficulties of obtaining a passport, the availability of transportation, 

the diplomatic arrangements with the governments concerned and the 

efforts displayed to send the deportee away;” but the Court warned 

that “under established precedents, too long a detention may justify 

the issuance of a writ of habeas corpus.”

Mr. Justice Paras, now Chief Justice, Mr. Justice Feria, Mr. 

Justice Perfecto, and the writer of this decision dissented. Mr. Jus

CHAPTER 9

JURISDICTION OF STATES

tice Feria and Mr. Justice Perfecto voted for outright discharge of the 

prisoner from custody. Mr. Justice Paras qualified his dissent by 

stating that he might agree “to a further detention of the herein 

petitioner, provided that he be released if after six months, the 

Government is still unable to deport him.” This writer joined in the 

latter dissent but thought that two months constituted reasonable time.

Over two years having elapsed since the decision aforesaid was 

promulgated, the Government has not found ways and means of 

removing the petitioner out of the country, and none are in sight, 

although, it should be said injustice to the deportation authorities, it 

was through no fault of theirs that no ship or country would take the 

petitioner.

Aliens illegally staying in the Philippines have no right of 

asylum therein (Soewapadji vs. Wixon, Sept. 18, 1946, 157 F. ed., 289, 

290), even if they are “stateless,” which the petitioner claims to be. It 

is no less true however, as impliedly stated in this Court’s decision, 

supra, that foreign nationals, not enemy, against whom no charge has 

been made other than that their permission to stay has expired, may 

not indefinitely be kept in detention. The protection against 

deprivation of liberty without due process of law and except for 

crimes committed against the laws of the land is not limited to 

Philippine citizens but extends to all residents, except enemy aliens, 

regardless of nationality. Whether an alien who entered the country in 

violation of its immigration laws may be detained for as long as the 

Government is unable to deport him, is a point we need not decide. 

The petitioner’s entry into the Philippines was not unlawful; he was 

brought by the armed and belligerent forces of a de facto government 

whose decrees were law during the occupation.

Moreover, by its Constitution (Art. II, Sec. 3), the Philippines 

“adopts the generally accepted principles of international law as part 

of the law of Nation.” And in a resolution entitled “Universal 

Declaration Of Human Rights” and approved by the General 

Assembly of the United Nations of which the Philippines is a 

member, at its plenary meeting on December 10, 1948, the right to 

life and liberty and all other fundamental rights as applied to all 

human beings were proclaimed. It was there resolved that “All human 

beings are bom free and equal in degree and rights” (Art. 1)\ that 

“Everyone is entitled to all the rights and freedom set forth in this 

Declaration, without distinction of any kind, such as race, colour, sex, 

language, religion, political or other opinion,

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

nationality or social origin, property, birth, or other status” (Art.

2) ; that “Every one has the right to an effective remedy by the 

competent national tribunals for acts violating the fundamental rights 

granted him by the Constitution or by law” (Art. 8); that “No one 

shall be subjected to arbitrary arrest, detention or exile” (Art. 9 ); etc.

The most recent case, as far as we have been able to find, was 

that of Staniszewski vs. Watkins (1948), 80 Fed. Supp., 132, which is 

nearly foursquare with the case at hand. In that case a stateless 

person, formerly a Polish national, resident in the United States since 

1911 and many times serving as a seaman on American vessels both 

in peace and in war, was ordered excluded from the United States and 

detained at Ellis Island at the expense of the steamship company, 

when he returned from a voyage on which he had shipped from New 

York for one or more European ports and return to the United States. 

The grounds for his exclusion were that he had no passport or 

immigration visa, and that in 1937 had been convicted of perjury 

because in certain documents he represented himself to be an 

American citizen. Upon his application for release on habeas corpus,

the Court released him upon his own recognizance. Judge Leibell, of 

the United States District Court for the Southern District of New 

York, said in part:

“When the return to the writ of habeas corpus came 

before this court, I suggested that all interested parties ... make 

an effort to arrange to have the petitioner ship out of some 

country that would receive him as a resident. He is a nativeborn Pole but the Polish Consul has advised him in writing that 

he is no longer a Polish subject. This Government does not 

claim that he is a Polish citizen. This attorney says he is 

stateless. The Government is willing that he go back to the 

ship, but if he were sent back aboard ship and sailed to the Port 

(Cherbourg, France) from which he last sailed to the United 

States, he would probably be denied permission to land. There 

is no other country that would take him, without proper 

documents.

“It seems to me that this is a genuine hardship case and 

that the petitioner should be released from custody on proper 

terms....

“What is to be done with the petitioner? The government 

has had him in custody almost seven months and prac

CHAPTER 9

JURISDICTION OF STATES

tically admits it has no place to send him out of this country. 

The steamship company, which employed him as one of a 

group sent to the ship by the Union, with proper seaman’s 

papers issued by the United States Coast Guard, is paying $3 a 

day for petitioner’s board at Ellis Island. It is no fault of the 

steamship company that petitioner is an inadmissible alien as 

the immigration officials describe him....

“I intend to sustain the writ of habeas corpus and order 

the release of the petitioner on his own recognizance. He will 

be required to inform the immigration officials at Ellis Island 

by mail on the 15th of each month, stating where he is 

employed and where he can be reached by mail. If the 

government does succeed in arranging for petitioner’s 

deportation to a country that will be ready to receive him as a 

resident, it may then advise the petitioner to that effect and 

arrange for his deportation in the manner provided by law.”

Although not binding upon this Court as a precedent, the case 

aforecited affords a happy solution to the quandary in which the 

parties here find themselves, solution which we think is sensible, 

sound and compatible with law and the Constitution. For this reason,

and since the Philippine law on immigration was patterned after or 

copied from the American law and practice, we choose to follow and 

adopt the reasoning and conclusions in the Stanisze- wski decision 

with some modifications which, it is believed, are in consonance with 

the prevailing conditions of peace and order in the Philippines.

Premises considered, the writ will issue commanding the 

respondents to release the petitioner from custody upon these terms: 

The petitioner shall be placed under the surveillance of the 

immigration authorities or their agents in such form and manner as 

may be deemed adequate to insure that he keep peace and be 

available when the Government is ready to deport him. The 

surveillance shall be reasonable and the question of reasonableness

shall be submitted to this Court or to the Court of First Instance of 

Manila for decision in case of abuse. He shall also put up a bond for 

the above purpose in the amount of P5,000 with sufficient surety or 

sureties, which bond the Commissioner of Immigration is authorized 

to exact by Section 40 of Commonwealth Act No. 613.

156 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The Protective Principle.

This principle says that a state may exercise jurisdiction over conduct 

outside its territory that threatens its security, as long as that conduct is generally 

recognized as criminal by states in the international community. (Restatement 

402[3]) This conditional clause excludes acts committed in exercise of the liberty 

guaranteed an alien by the law of the place where the act was committed.

The examples given of acts covered by the protective principle are plots to 

overthrow the government, forging its currency, and plot to break its immigration 

regulations. A sample case of this is that of “Lord Haw Haw,” an American citizen 

who broadcast messages from Germany seeking to persuade the Allies to 

surrender. Until 1940, he held a British passport. After the war, he was convicted 

of high treason in the United Kingdom. In upholding the principle, Lord Jowwit of 

the House of Lords said: “No principle of comity demands that a state should 

ignore the crime of treason committed against it outside its territory. On the 

contrary, a proper regard for its own security requires that all those who commit 

that crime, whether they commit it within or without the realm should be amenable 

to its laws.”1

The limitations on the protective principle are found in United States v. 

Yunis?

[. . . Because this principle gives states wide latitude in defining 

the parameters of their jurisdiction, the international community has 

strictly construed the reach of this doctrine to those offenses posing a 

direct, specific threat to national security. See Blakesley, United States 

Jurisdiction over Extraterritorial Crime,

73 J.CrimL. & Criminology at 1136; Bassiouini, II International 

Criminal Law ch. 2 at 21. Recently, some academicians have urged a 

more liberal interpretation of the protective principle when applied to 

terroristic activities. Given “the increase in the number of terroristic 

threats against United States nationals abroad, there can be no doubt 

that the United States has significant security and protective interests 

at stake.” Paust, Federal Jurisdiction over Extraterritorial Acts of 

Terrorism, 23 VaJ. oflnt’l Law 191, 210 (1983). In this case, the 

hijackers never made any demands upon the United States 

government nor directly threatened its security.

Prosecutions, House of Lords

CHAPTER 9

JURISDICTION OF STATES

157

Indeed, it was almost happenstance that three American nationals 

were on board the aircraft. Given the regional focus of the hijacking, a 

court would have to adopt an expansive view of the principle to assert 

jurisdiction over Yunis. Since jurisdiction is available under the 

universality and passive personality principle, there is no reason to 

reach out and rely on the protective principle as well.]

The Universality Principle.

The universality principle recognizes that certain activities, universally 

dangerous to states and their subjects, require authority in all community members 

to punish such acts wherever they may occur, even absent a link between the state 

and the parties or the acts in question. This principle started with piracy. Piracy in 

international law means any illegal act of violence or depredation committed for

private ends on the high seas or outside the territorial control of any state. Now the 

principle covers not just piracy but also genocide, crimes against humanity, war 

crimes, aircraft piracy and terrorism. There is also a growing support for universal 

jurisdiction over crimes against human rights.

The Statute of the new International Criminal Court defines these crimes,

thus:

Article 6. Genocide

For the purpose of this Statute, “genocide" means any of the 

following acts committed with intent to destroy, in whole or in part, a 

national, ethnical, racial or religious group, as such:

(a) Killing members of the group;

(b) Causing serious bodily or mental harm to members of the 

group;

(c) Deliberately inflicting on the group conditions of life 

calculated to bring about its physical destruction in whole or in part;

(d) Imposing measures intended to prevent births within the

group;

(e) Forcibly transferring children of the group to another 

group.

Article 7. Crimes against humanity

1. For the purpose of this Statute, “crime against humanity” means any of the following acts when committed as part of

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

a wide-spread or systematic attack directed against any civilian 

population, with knowledge of the attack:

(e) Imprisonment or other severe deprivation of 

physical liberty in violation of fundamental rules of international law;

(f) Torture;

pregnancy, enforced sterilization, or any other form of sexual 

violence of comparable gravity;

(h) Persecution against any identifiable group or 

collectivity on political, racial, national, ethnic, cultural,

that are universally recognized as impermissible under 

international law, in connection with any act referred to in this 

paragraph or any crime within the jurisdiction of the Court;

(i) Enforced disappearance of persons;

(j) The crime of apartheid;

(k) Other inhumane acts of a similar character in

tentionally causing great suffering, or serious injury to body or 

to mental or physical health.

2. For the purpose of paragraph 1:

(a) “Attack directed against any civilian population"

means a course of conduct involving the multiple commission 

of acts referred to in paragraph 1 against any civilian 

population, pursuant to or in furtherance of a State or 

organizational policy to commit such attack;

(b) “Extermination ” includes the intentional infliction 

of conditions of life, inter alia the deprivation of access to food 

and medicine, calculated to bring about the destruction of part 

of a population;

(c) “Enslavement” means the exercise of any or all of 

the powers attaching to the right of ownership over a person 

and includes the exercise of such power in the course of

CHAPTER 9

JURISDICTION OF STATES

(d) “Deportation or forcible transfer of population"

means forced displacement of the persons concerned by 

expulsion or other coercive acts from the area in which they are 

lawfully present, without grounds permitted under international 

law;

(e) “Torture" means the intentional infliction of 

severe pain or suffering, whether physical or mental, upon a 

person in the custody or under the control of the accused; 

except that torture shall not include pain or suffering arising 

only from, inherent in or incidental to, lawful sanctions;

(f) “Forced pregnancy" means the unlawful confinement of a woman forcibly made pregnant, with the intent of 

affecting the ethnic composition of any population or carrying 

out other grave violations of international law. This definition 

shall not in any way be interpreted as affecting national laws 

relating to pregnancy;

(g) “Persecution ” means the intentional and severe 

deprivation of fundamental rights contrary to international law 

by reason of the identity of the group or collectivity;

(h) “The crime of apartheid" means inhumane acts of 

a character similar to those referred to in paragraph 1, 

committed in the context of an institutionalized regime of 

systematic oppression and domination by one racial group over 

any other racial group or groups and committed with the 

intention of maintaining that regime;

(i) “Enforced disappearance of persons” means the 

arrest, detention or abduction of persons by, or with the 

authorization, support or acquiescence of, a State or a political

whereabouts of those persons, with the intention of removing 

them from the protection of the law for a prolonged period of 

time.

3. For the purpose of this Statute, it is understood that the 

term “gender” refers to the two sexes, male and female, within the 

context of society. The term “gender” does not indicate any meaning 

different from the above.

Article 8. War crimes

1. The Court shall have jurisdiction in respect of war crimes 

in particular when committed as part of a plan or policy or as part of a 

large-scale commission of such crimes.

160 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

2. For the purpose of this Statute, “war crimes” means:

(a) Grave breaches of the Geneva Conventions of 12 

August 1949, namely, any of the following acts against persons 

or property protected under the provisions of the relevant 

Geneva Convention. ...

Article 8 enumerates in detail the war crimes under the Geneva Convention.

The following are a number of cases illustrative of the universality principle:

F1LARTIGA V. PENA-IRALA 630 FJD 876. (1980)

[This was a wrongful death action which was brought by two 

nationals of Paraguay, the father and sister of a 17-year old 

Paraguayan, who, it was alleged, was tortured to death in Paraguay by 

the defendant Pena-Irala who at the time was Inspector-General of the 

police. Jurisdiction was claimed principally on the basis of the Alien 

Tort Statute (28 U.S.C. & 1350). The Court held that deliberate 

torture under the color of official authority violated the universal rules 

of international law regardless of the nationality of the parties. In 

reaching the conclusion that the prohibition of torture has become part 

of customary international law, the Court referred as evidence to the 

Universal Declaration of Human Rights and as particularly relevant, 

the 1975 Declaration on the Protection of all Persons from Torture.

[The relevant portions of the Court’s opinion read as follows:]

The Declaration goes on to provide that “[w]here it is proved 

that an act of torture or other cruel, inhuman or degrading treatment 

or punishment has been committed by or at the instigation of a public 

official, the victim shall be afforded redress and compensation, in 

accordance with national law.” This Declaration, like the Declaration 

of Human Rights before it, was adopted without dissent by the 

General Assembly. Nayar, “Human Rights: The United Nations and 

United States Foreign Policy,” 19 Harv. Int’l LJ. 813, 816 n. 18 

(1978).

These U.N. declarations are significant because they specify with great 

precision the obligations of member nations under the Charter.

CHAPTER 9

JURISDICTION OF STATES

161

Since their adoption, “[m]embers can no longer contend that they do not know 

what human rights they promised in the Charter to promote.” Sohn, “A Short 

History of United Nations Documents on Human Rights," in the The United 

Nations and Human Rights, 18th Report of the Commission (Commission to 

Study the Organization of Peace [Ed., 1968]).... Accordingly, it has been observed 

that the Universal Declaration of Human Rights “no longer fits into the dichotomy 

of ‘binding treaty’ against ‘non-binding pronouncement,’ but is rather an authoritative statement of the international community.” E. Schwelb, Human Rights and 

the International Community 70 (1964). Thus, a Declaration creates an 

expectation of adherence, and “insofar as the expectation is gradually justified by 

State practice, a declaration, may by custom become recognized as laying down 

rules binding upon the States.” 34 UN. ESCOR, supra. Indeed, several 

commentators have concluded that the Universal Declaration has become, in toto, 

a part of binding, customary international law. Nayar, supra, at 816-17; Waldock, 

“Human Rights in Contemporary International Law and the Significance of the 

European Convention, ” I.C.L.Q., Supp.Publ. No. 11 at 15 (1965).

Turning to the act of torture, we have little difficulty discerning its universal 

renunciation in the modern usage and practice of nations. Smith, supra, 18 US. (5 

Wheat.) at 160-61,5 L.Ed. 57. The international consensus surrounding torture has 

found expression in numerous international treaties and accords.... The substance 

of these international agreements is reflected in modem municipal — i.e., national 

— law as well. Although torture was once a routine concomitant with criminal 

interrogations in many nations, during the modem and hopefully more enlightened 

era it has been universally renounced. According to one survey, torture is 

prohibited, expressly or implicitly, by the constitutions of over fifty-five nations, 

including both the United States and Paraguay. Our State Department reports a 

general recognition of this principle:

There now exists an international consensus that recognizes basic human 

rights and obligations owed by all governments to their citizens. ... There is no 

doubt that these rights are often violated; but virtually all governments 

acknowledge their validity.

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

ATTORNEY GENERAL OF ISRAEL v. EICHMANN Trial Court 

Decision

36 Intl. L. Rep. 5 (Israel, Dist. Ct. Jerusalem 1961)

Adolf Eichmann was a high ranking SS officer who played a 

central role in the planning and implementation of the persecution of 

Jews in Germany, Poland, Hungary and several other countries 

before and during World War II. At the end of the war, he escaped to 

Argentina where he lived and worked under an alias until May,

1960 when he was kidnapped by Israeli agents. Argentina complained to the Security Council about this clear violation of Argentine 

sovereignty. The Security Council, while making it clear that it did 

not condone Eichmann’s crimes, declared that, “acts such as that 

under consideration [the kidnapping of Eichmann] which affect the 

sovereignty of a Member State and therefore cause international 

friction, may, if repeated, endanger international peace and security.” 

The Security Council requested the Government of Israel “to make 

appropriate reparation in accordance with the Charter of the United 

Nations and the rules of international law.” Argentina did not demand 

the return of Eichmann, and in August,

1960, the Argentine and Israeli governments resolved in a joint 

communique “to regard as closed the incident which arose out of the 

action taken by citizens of Israel, which infringed the fundamental 

rights of the State of Argentina.”

Eichmann was then tried in Israel under Israel’s Nazi Collaborators Law (a law enacted after Israel became a state in 1948).

He was found guilty and the conviction was subsequently upheld by 

the Supreme Court of Israel. On May 31,1962, Eichmann went to the 

gallows, the only person ever formally executed by the State of 

Israel.

Learned defence counsel... submits:

(a) that the Israel Law, by imposing punishment for acts done 

outside the boundaries of the State and before its establishment, against 

persons who were not Israel citizens, and by a person who acted in the 

course of duty on behalf of a foreign country (“Act of State”), conflicts with 

international law and exceeds the powers of the Israel Legislature;

(b) that the prosecution of the accused in Israel following his 

abduction from a foreign country conflicts with international law and 

exceeds the jurisdiction of the Court....

CHAPTER 9

JURISDICTION OF STATES

163

From the point of view of international law, the power of the State of 

Israel to enact the Law in question or Israel’s “right to punish” is based, 

with respect to the offences in question, on a dual foundation: the universal 

character of the crimes in question and their specific character as intended to 

exterminate the Jewish people....

12. The abhorrent crimes defined in this Law are not crimes under 

Israel law alone. These crimes, which struck at the whole of mankind and 

shocked the conscience of nations, are grave offenses against the law of 

nations itself (delicta juris gentium). Therefore, so far from international 

law negating or limiting the jurisdiction of countries with respect to such 

crimes, international law is, in the absence of an International Court, in need 

of the judicial and legislative organs of every country to give effect to its 

criminal interdictions and to bring the criminals to trial. The jurisdiction to 

try crimes under international law is universal....

26. ... It is superfluous to add that the “crime against the Jewish 

people,” which constitutes the crime of “genocide”, is nothing but the 

gravest type of “crime against humanity” (and all the more so because both 

under Israel law and under the Convention a special intention is requisite for 

its commission, an intention that is not required for the commission of a 

“crime against humanity”). Therefore, all that has been said in the 

Nuremberg principles about “crimes against humanity” applies a fortiori to 

crime against the Jewish people.” ...

27. ... It is indeed difficult to find a more convincing instance of a 

just retroactive law than the legislation providing for the punishment of war 

criminals and perpetrators of crimes against humanity and against the 

Jewish people, and all the reasons justifying the Nuremberg judgments 

justify eo ipse the retroactive legislation of the Israel legislator. ... The 

accused in this case is charged with the implementation of the plan for the 

“final solution of the problem of the Jews.” Can anyone in his right mind 

doubt the absolute criminality of such acts? ...

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

28. ... The contention of learned counsel for the defense

that it is not the accused but the State on whose behalf he had acted, who is 

responsible for his criminal acts is only true as to its second part. It is true 

that under international law Germany bears not only moral, but also legal, 

responsibility for all the crimes that were committed as its own “acts of 

State,” including the crimes attributed to the accused. But that responsibility 

does not detract one iota from the personal responsibility of the accused for 

his acts....

EICHMANN V. ATTORNEY-GENERAL OF ISRAEL Supreme 

Court of Israel (1962) 136 IIJl. 277

Judgment Per Curiam:

The crimes created by the Law and of which the appellant was 

convicted must be deemed today to have always borne the stamps of 

international crimes, banned by international law and entailing 

individual criminal liability. It is the particular universal character of 

these crimes that vests in each State the power to try and punish any 

who assisted in their commission. . . . [Reference the Genocide 

Convention and the Nuremberg judgment]..

... As is well known, the rules of the law of nations are not 

derived solely from international treaties and crystallized international 

usage. In the absence of a supreme legislative authority and 

international codes, the process of its evolution resembles that of the 

common law;... its rules are established from case to case, by analogy 

with the rules embodied in treaties and in intentional custom, on the 

basis of the “general” principles of law recognized by civilized 

nations,” and in the light of the vital international needs that impel an 

immediate solution. A principle which constitutes a common 

denominator for the judicial systems of numerous countries must 

clearly be regarded as a “general principle of law recognized by 

civilized nations.” ... [C]ustomary international law is never stagnant, 

but is rather in a process of constant growth....

... [As to] the features which identify crimes that have long 

been recognized by customary international law[,] ... they constitute 

acts which damage vital international interests ... they impair

CHAPTER 9

JURISDICTION OF STATES

the foundations and security of the international community; they 

violate universal moral values and humanitarian principles which are 

at the root of the systems of criminal law adopted by civilized nations. 

The underlying principle in intentional law that governs such crimes 

is that the individual who has committed any of them and who, at the 

time of his act, may be presumed to have had a thorough 

understanding of its heinous nature must account in law for his 

behavior. It is true that intentional law does not establish explicit and 

graduated criminal sanctions; that there is not as yet in existence 

either an intentional Criminal Court, or intentional machinery for the 

imposition of punishment. But, for the time being, intentional law 

surmounts these difficulties ... by authorizing the countries of the 

world to mete out punishment for the violation of its provisions. This 

they do by enforcing these provisions either directly or by virtue of

the municipal legislation which has adopted and integrated them....

The classic example of a “customary” international crime ... is 

that of piracy jure gentium. ... [Another] example ... is that of a “ war 

crime “ in the conventional sense. ... the group of acts committed by 

members of the armed forces of the enemy which are contrary to the 

“’laws and customs of war.” individual criminal responsibility 

because they undermine the foundations of intentional society and are 

repugnant to the conscience of civilized nations. When the belligerent 

State punishes for such acts, it does so not only because persons who 

were its nationals ... suffered bodily harm or material damage, but 

also, and principally, because they involve the perpetration of an 

intentional crime in the avoidance of which all the nations of the 

world are interested....

In view of the characteristic traits of international crimes and 

the organic development of the law of nations — a development that 

advances from case to case under the impact of the humane 

sentiments common to civilized nations, and under the pressure of the 

needs that are vital for the survival of mankind and for ensuring the 

stability of the world order it definitely cannot be said that when the 

Charter of the Nuremburg International Military Tribunal was signed 

and the categories of “war crimes” and “crimes against humanity” 

were defined in it, this merely amounted to an act of legislation by the 

victorious countries....

... [The interest in preventing and imposing punishment for acts 

comprised in the category in question especially when they are 

perpetrated on a very large scale — must necessarily extend beyond 

the borders of the State to which the perpetrators belong

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

and which evinced tolerance or encouragement of their outrages; for 

such acts can undermine the foundations of the international 

community as a whole and impair its very stability....

If we are to regard customary international law as a developing 

progressive system, the criticism becomes devoid of value.... [E]ver 

since the Nuremberg Tribunal decided this question, that very 

decision must be seen as a judicial act which establishes a 

“precedent” defining the rule of international law. In any event, it 

would be unseemly for any other court to disregard such a rule and 

not to follow it. ...

If there was any doubt as to this appraisal of the ‘“Nuremberg 

Principles’ as principles that have formed part of customary 

international law since time immemorial,” such doubt has been 

removed by ... the United Nations Resolution on the Affirmation of 

the Principles of International Law Recognized by the Charter and 

Judgment of the Nuremberg Tribunal and that affirming that 

Genocide is a crime under intentional law ... and as [is seen] in the 

advisory opinion of 1951 ... the principles inherent in the [Genocide] 

Convention — as distinct from the contractual obligations embodied 

therein — had already been part of customary intentional law at the 

time of the shocking crimes which led to the Resolution and the 

Convention....

... [T]he crimes established in the Law of 1950 ... must be seen 

today as acts that have always been forbidden by customary 

international law — acts which are of a “universal” criminal character

and entail individual criminal responsibility. ... [T]he enactment of 

the Law was not, from the point of view of international law, a 

legislative act that conflicted with the principle nulla poena or the 

operation of which was retroactive, but rather one by which the 

Knesset gave effect to intentional law and its objectives....

... [I]t is the universal character of the crimes in question which

vests in every State the power to try those who participated in the 

preparation of such crimes, and to punish them therefor....

One of the principles whereby States assume, in one degree or 

another, the power to try and punish a person for an offence he has 

committed is the principle of universality. Its meaning is, in essence, 

that that power is vested in every State regardless of the fact that the 

offence was committed outside its territory by a person who did not 

belong to it, provided he is in its custody at the time he is brought to 

trial. This principle has wide support and is universally acknowledged 

with respect to the offence of piracy jure

CHAPTER 9

167

gentium.... [One view] holds that it cannot be applied to any other 

offence, lest this entail excessive interference with the competence of 

the State in which the offence was committed.

The Passive Personality Principle.

The Comment on § 402 of Third Restatement says: “The passive personality 

principle asserts that a state may apply law — particularly criminal law — to an 

act committed outside its territory by a person not its national where the victim of 

the act was its national. The principle has not been ordinarily accepted for ordinary 

torts or crimes, but it is increasingly accepted as applied to terrorist and other 

organized attacks on a state’s nationals by reason of their nationality, or to 

assassination of a state’s diplomatic representatives or other officials.”

UNITED STATES v. FAWAZ YUNIS 681 FJSupp. 8961 (1988)

This criminal proceeding and indictment arise from the 

hijacking of a Jordanian civil aircraft, Royal Jordanian Airlines 

(“ALIA”) Flight 402, on June 11, and 12, 1985. There is no dispute 

that the only nexus to the United States was the presence of several 

American nationals on board the flight. The airplane was registered in 

Jordan, flew the Jordanian flag and never landed on American soil or 

flew over American airspace.

On the morning of June 11, the aircraft was positioned at the 

Beirut International Airport, Beirut, Lebanon, for a scheduled 

departure to Amman, Jordan. As the 50-60 passengers boarded, 

several Arab men, one allegedly the defendant, stormed the plane and 

ordered the pilot to fly to Tunis, Tunisia where a meeting of the Arab 

League Conference was underway. The airplane departed from Beirut 

with all passengers, including the Americans, held hostage. The plane 

made a short landing in Lamaco, Cyprus where additional fuel was 

obtained. It then proceeded to Tunis where landing privileges were 

denied. The airplane flew to Palermo, Sicily, where it was allowed to 

replenish its fuel and food supply. Thereafter, it lifted off, destined 

once more for Tunis. Again, entry was denied and the pilot returned 

to Beirut. On the morning of June 12th, it took off for Damascus, 

Syria. However, the Syrian authorities also denied landing privileges. 

Thus, after criss-crossing the Mediterranean Sea area for more than 

30 hours, the hijackers were forced to return to Beirut, their point of 

initial departure.

168 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

After landing, the hostages were directed to exit the aircraft.

The hijackers then called an impromptu press conference and the 

defendant Yunis allegedly read a speech, which he originally 

intended to give to the delegates of the Arab League Conference then 

meeting in Tunis. Following the speech, the hijackers blew up the 

Jordanian aircraft, quickly left the scene and vanished into the Beirut 

landscape.

Between June 11 and 12, 1985, ALIA Flight 402 never landed 

on or flew over American space. Its flightpath was limited to an area 

within and around the Mediterranean Sea. Based on the absence of 

any nexus to United States territory, Yunis has moved to dismiss the 

entire indictment, arguing that no United States federal court has 

jurisdiction to prosecute a foreign national for crimes committed in 

foreign airspace and on foreign soil. He further claims that the 

presence of the American nationals on board the aircraft is an 

insufficient basis for exercising jurisdiction under principles of 

international law.

Defendant’s motion raises several threshold inquiries: whether 

or not there is a basis for jurisdiction under international law, and if 

so, whether Congress intended to and had authority to extend 

jurisdiction of our federal courts over criminal offenses and events 

which were committed and occurred overseas and out of the 

territorial jurisdiction of such courts.

II.

ANALYSIS

A. JURISDICTION UNDER INTERNATIONAL LAW

The parties agree that there are five traditional bases of jurisdiction over 

extraterritorial crimes under international law: Territorial, wherein jurisdiction is 

based on the place where the offense is committed; National, wherein jurisdiction 

is based on the nationality of the offender; Protective, wherein jurisdiction is 

based on whether the national interest is injured; Universal, wherein jurisdiction is 

conferred in any forum that obtains physical custody of the perpetuator of certain 

offenses considered particularly heinous and harmful to humanity. Passive 

personal, wherein jurisdiction is based on the nationality of the victim.

These general principles were developed in 1935 by a Harvard Research

Project in an effort to codify principles of jurisdiction under

CHAPTER 9 169

JURISDICTION OF STATES

international law. See Harvard Research in International Law, Jurisdiction with 

Respect to Crime, 29 AmJlnt’l L. 435, 445 (Supp.1935). Most courts, including 

our Court of Appeals, have adopted the Harvard Research designations on 

jurisdiction. ... Several reputable treatises have also recognized the principles: L. 

Henkin, International Law Cases and Materials 447 (1980); A. D’Amato, 

International Law and World Order 564 (1980).

The Universal and the Passive Personal principle appear to offer potential 

bases for asserting jurisdiction over the hostage-taking and aircraft piracy charges 

against Yunis. However, his counsel argues that the Universal principle is not 

applicable because neither hostage-taking nor aircraft piracy are heinous crimes 

encompassed by the doctrine. He urges further, that the United States does not 

recognize Passive Personal as a legitimate source of jurisdiction. The government 

flatly disagrees and maintains that jurisdiction is appropriate under both.

1. Universal Principle

[1] The Universal principle recognizes that certain offenses are so heinous 

and so widely condemned that “any state if it captures the offender may prosecute 

and punish that person on behalf of the world community regardless of the 

nationality of the offender or victim or where the crime was committed.” M. 

Bassiouini, II International Criminal Law, Ch. 6 at 298 (Ed. 1986). The crucial 

question for purposes of defendant’s motion is how crimes are classified as 

“heinous” and whether aircraft piracy and hostage taking fit into this category.

Those crimes that are condemned by the world community and subject to 

prosecution under the Universal principal are often a matter of international 

conventions or treaties. See Demjanjuk v. Petrovsky, 776 F.2d 571, 582 (6th Cir. 

1985). (Treaty against genocide signed by a significant number of states made that 

crime heinous; therefore, Israel had proper jurisdiction over nazi war criminal 

under the Universal principle.)

Both offenses are the subject of international agreements. A majority of 

states ii\ the world community including Lebanon, have signed three treaties

condemning aircraft piracy: The Tokyo Convention, The Hague Convention, and 

The Montreal Convention. The Hague and Montreal Conventions explicitly rely 

on the princ^le of Universal jurisdiction in mandating that all states “take such 

measures as may

170 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

be necessary to establish its jurisdiction over the offences ... where the alleged 

offender is present in its territory.” Hague Convention Art. 4 s 2; Montreal 

Convention Art. 5 s 2. Further, those treaties direct that all “contracting states ... of 

which the alleged offender is found,... shall, be obliged, without exception 

whatsoever and whether or not the offense was committed in its territory, to 

submit the case to its competent authorities for the purpose of prosecution.” 

Hague Convention, Art. 7; Montreal Convention, Art. 7. (emphasis added) These 

two provisions together demonstrate the international community’s strong 

commitment to punish aircraft hijackers irrespective of where the hijacking 

occurred.

The global community has also joined together and adopted the 

International Convention for the Taking of Hostages, an agreement which 

condemns and criminalizes the offense of hostage taking. Like the conventions 

denouncing aircraft piracy, this treaty requires signatory states to prosecute any 

alleged offenders “present in its territory.”

In light of the global efforts to punish aircraft piracy and hostage taking, 

international legal scholars unanimously agree that these crimes fit within the 

category of heinous crimes for purposes of asserting universal jurisdiction. See M. 

Bassiouini, II International Criminal Law Ch. 2 at 31-32; McCredie, 

Contemporary Uses of Force Against Terrorism, 1986 GaJ. oflnt’l & Comp.L. 

435,439 (1986); Bazyler, Capturing the Terrorist in the Wild Blue Yonder, 8 

Whittier L.Rev. 685,687 (1986); Blakesley, United States Jurisdiction over 

Extraterritorial Crime, 73 J. ofCrim.L. & Criminology 1109,1140 (1982). In The 

Restatement (Revised) of Foreign Relations Law of the United States, a source 

heavily relied upon by the defendant, aircraft hijacking is specifically identified as 

a universal crime over which all states should exercise jurisdiction.

Our Circuit has cited the Restatement with approval and determined that the 

Universal principle, standing alone, provides sufficient basis for asserting 

jurisdiction over an alleged offender. See Tel-Oren v. Libyan Arab Republic, 726 

F.2d at 781, n. 7. (“The premise of universal jurisdiction is that a state ‘may 

exercise jurisdiction to define and punish certain offenses recognized by the 

community of nations as of universal concern,’... even where no other recognized 

basis of jurisdiction is present.”) Therefore, under recognized principles of 

international law, and the law of thip Circuit, there is clear authority to assert 

jurisdiction over Yunis for the offenses of aircraft piracy and hostage taking.

CHAPTER 9

JURISDICTION OF STATES

171

2. Passive Personality Principle

This principle authorizes states to assert jurisdiction over offenses 

committed against their citizens abroad. It recognizes that each state has a 

legitimate interest in protecting the safety of its citizens when they journey outside 

national boundaries. Because American nationals were on board the Jordanian 

aircraft, the government contends that the Court may exercise jurisdiction over 

Yunis under this principle. Defendant argues that this theory of jurisdiction is 

neither recognized by the international community nor the United States and is an 

insufficient basis for sustaining jurisdiction over Yunis.

Although many international legal scholars agree that the principle is the 

most controversial of the five sources of jurisdiction, they also agree that the 

international community recognizes its legitimacy. Most accept that “the 

extraterritorial reach of a law premised upon the ... principle would not be in doubt 

as a matter of international law.” Paust, Jurisdiction and Nonimmunity, 23 Va. J. 

oflnt’l Law, 191, 203 (1983). More importantly, the international community 

explicitly approved of the principle as a basis for asserting jurisdiction over 

hostage takers. As noted above, supra p. 9, the Hostage Taking Convention set 

forth certain mandatory sources of jurisdiction. But it also gave each signatory 

country discretion to exercise extraterritorial jurisdiction when the offense was 

committed “with respect to a hostage who is a national of that state if that state 

considers it appropriate.” Art. 5(a)(d). Therefore, even if there are doubts 

regarding the international community’s acceptance, there can be no doubt 

concerning the application of this principle to the offense of hostage taking, an 

offense for which Yunis is charged. See M. Bassiouni, II International Criminal 

Law ch. 4 at 120.

Defendant’s counsel correctly notes that the Passive Personal principle 

traditionally has been an anathema to United States lawmakers. But his reliance on 

the Restatement (Revised) of Foreign Relations Laws for the claim that the United 

States can never invoke the principle is misplaced. In the past, the United States 

has protested any assertion of such jurisdiction for fear that it could lead to 

indefinite criminal liability for its own citizens. This objection was based on the 

belief that foreigners visiting the United States should comply with our laws and 

should not be permitted to carry their laws with them. Otherwise Americans would

them as illegal. However, in the most recent draft of the Restatement, the authors 

noted that the theory “has been increasingly accepted when applied to terrorist and 

other organized attacks on a state’s nationals by reason of their nationality, or to 

assassinations of a state’s ambassadors, or government officials.” Restatement 

(Revised) s 402, comment g (Tent. Draft No. 6). See also McGinley, The Achillo 

Lauro Affair-Implications for International Law, 52 TennLRev. 691, 713 (1985).

The authors retreated from their wholesale rejection of the principle, recognizing 

that perpetrators of crimes unanimously condemned by members of the 

international community, should be aware of the illegality of their actions.] 

Therefore, qualified application of the doctrine to serious and universally 

condemned crimes will not raise the specter of unlimited and unexpected criminal 

liability.

Finally, this case does not present the first time that the United States has 

invoked the principle to assert jurisdiction over a hijacker who seized an American 

hostage on foreign soil. The government relied on this very principle when it 

sought extradition of Muhammed Abbas Zaiden, the leader of the terrorists who 

hijacked the Achillo Lauro vessel in Egyptian waters and subsequently killed Leon 

Klinghoffer, an American citizen. As here, the only connection to the United 

States was Klinghoffer’s American citizenship. Based on that link, an arrest 

warrant was issued charging Abbas with hostage taking, conspiracy and piracy. Id. 

at 719; See also N.Y. Times, Oct. 16,1985 s 1 at 1 col. 6.

Thus, the Universal and Passive Personality principles, together, provide 

ample grounds for this Court to assert jurisdiction over Yunis. In fact, reliance on 

both strengthens the basis for asserting jurisdiction. Not only is the United States 

acting on behalf of the world community to punish alleged offenders of crimes 

that threaten the very foundations of world order, but the United States has its own 

interest in protecting its nationals.

Conflicts of jurisdiction.

Since there are various accepted principles for assuming jurisdiction, more 

than one state may have a valid claim to jurisdiction. U.S. courts have attempted to 

develop more sophisticated modes of resolving conflict of jurisdiction. Three 

modes are given below.

CHAPTER 9

JURISDICTION OF STATES

173

The Balancing Test

In Timberlane Lumber Co. v. Bank of America? the question was whether 

to assume jurisdiction in a Sherman Act case involving acts emanating from 

Honduras. The court employed a tripartite analysis to determine whether to 

assume jurisdiction or not. First, was there an actual or intended effect on 

American foreign commerce. Second, is the effect sufficiently large to present a 

cognizable injury to the plaintiffs and, therefore, a civil violation of the anti-trust 

laws. Third, are the interests of, and link to, the United States . . . including effects 

on American foreign commerce sufficiently strong, vis-d-vis those of other 

nations, to justify an assertion of extraordinary authority. If the answer is yes to all 

these, then the court will assume jurisdiction.

International Comity

Even when a state has basis for exercising jurisdiction, it will refrain from 

doing so if its exercise will be unreasonable. This is treated in Hartford Fire 

Insurance Co. v. California,

4

but the principle involved is summed up in Third 

Restatement §§ 403. Unreasonableness is determined by evaluating various 

factors, such as the link of the activity to the territory of the regulating state, the 

connection, such as nationality, residence, or economic activity, between the 

regulating state and the person principally responsible for the activity to be 

regulated, the character of the activity to be regulated, the existence of justified 

expectations that might be protected or hurt by the regulation, the likelihood of 

conflict with regulation by another state.

Forum non conveniens

The principle of forum non conveniens is well-stated in the following 

excerpt from a Scottish decision:

If in the whole circumstances of the case it be discovered that there is 

a real unfairness to one of the suitors in permitting the choice of a forum 

which is not the natural or proper forum, either on the ground of 

convenience of trial or the residence or domicile of parties or of its being the 

locus contractus, or locus solutionis, then the doctrine of forum non 

conveniens is properly applied.

174 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The application is discretionary with the court. Some of the interests which 

the court needs to weigh are divided into private interest factors and public interest 

factors. The private interest factors are access to sources of proof, availability of 

compulsory process for unwilling witnesses and other personal problems which 

make trial easy, expeditious and inexpensive. Public interest factors include 

congestion, desire to settle local controversies at home, and having the case tried 

in a forum at home with the applicable law. Forum non conveniens presumption is 

with the plaintiff. Piper Aircraft Co. v. Reyno,

5

is a leading application of the 

principle.

Extradition.

Extradition is the surrender of an individual by the state within whose

territory he is found to the state under whose laws he is alleged to have committed 

a crime or to have been convicted of a crime. It is a process that is governed by 

treaty. The legal right to demand extradition and the correlative duty to surrender a 

fugitive exist only when created by treaty. A treaty may cover specific crimes only 

or all offenses considered criminal by both states. Today most treaties exclude 

religious and political offenses, although political offenses have never been 

precisely defined. But a state may surrender a fugitive if surrendering him is not 

contrary to the state’s constitution.

The following principles govern extradition: (1) No state is obliged to 

extradite unless there is a treaty; (2) Differences in legal system can be an obstacle 

to interpretation of what the crime is; (3) Religious and political offenses are not 

extraditable.

The procedure for extradition is normally through diplomatic channels. The 

following case of United States v. Alvarez-Chain is an example of how 

extradition rules can be bypassed.

UNITED STATES v. ALVAREZ-MACHAIN 504UJS.655 (1992)

CHIEF JUSTICE REHNQUIST delivered the opinion of the 

Court.

The issue in this case is whether a criminal defendant, abducted 

to the United States from a nation with which it has an

454U.S. 235 (1981).

CHAPTER 9

JURISDICTION OF STATES

extradition treaty, thereby acquires a defense to the jurisdiction of this 

country’s courts. We hold that he does not, and that he may be tried in 

federal district court for violations of the criminal law of the United 

States.

Accused was indicted for participating in the kidnap and

murder of United States Drug Enforcement Administration (DEA) 

special agent Enrique Camarena-Salazar and a Mexican pilot working 

with Camarena, Alfredo Zavala-Avelar. The DEA believes that 

respondent, a medical doctor, participated in the murder by prolonging agent Camarena’s life so that others could further torture and 

interrogate him. On April 2, 1990, respondent was forcibly kidnapped 

from his medical office in Guadalajara, Mexico, to be flown by 

private plane to El Paso, Texas, where he was arrested by DEA 

officials. The District Court concluded that DEA agents were 

responsible for respondent’s abduction, although they were not 

personally involved in it. United States v. Caro-Quintero, 745 FSupp. 

599, 602-604, 609 (CD Cal. 1990).

Respondent moved to dismiss the indictment, claiming that his 

abduction constituted outrageous governmental conduct, and that the 

District Court lacked jurisdiction to try him because he was abducted 

in violation of the extradition treaty between the United States and 

Mexico. ... The District Court rejected the outrageous governmental 

conduct claim, but held that it lacked jurisdiction to try respondent

because his abduction violated the Extradition Treaty. The District 

Court discharged respondent and ordered that he be repatriated to 

Mexico. Caro-Quintero, supra, at 614.

The Court of Appeals affirmed the dismissal of the indictment 

and the repatriation of respondent...

In Ker v. Illinois, 119 U.S. 436 (1886) ... written by Justice 

Miller ... we addressed the issue of a defendant brought before the 

court by way of a forcible abduction. Frederick Ker had been tried 

and convicted in an Illinois court for larceny; his presence before the 

court was procured by means of forcible abduction from Peru. A 

messenger was sent to Lima with the proper warrant to demand Ker 

by virtue of the extradition treaty between Peru and the United States. 

The messenger, however, disdained reliance on the treaty processes, 

and instead forcibly kidnapped Ker and brought him to the United 

States. We ... rejected Ker’s due process argument more broadly, 

holding in line with “the highest authorities,” that such forcible 

abduction is no sufficient reason why the party should not

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

answer when brought within the jurisdiction of the court which has 

the right to try him for such an offence, and presents no valid 

objection to his trial in such court. Ker, supra, at 444.

In Frisbie v. Collins, 342 US. 519, rehearing denied, 343 U.S. 

937 (1952), we applied the rule in Ker to a case in which the 

defendant had been kidnaped in Chicago by Michigan officers and 

brought to trial in Michigan. We upheld the conviction over objections based on the Due Process Clause and the Federal Kidnapping 

Act, and stated:

“This Court has never departed from the rule announced 

in [Ker] that the power of a court to try a person for crime is 

not impaired by the fact that he had been brought within the 

court’s jurisdiction by reason of a ‘forcible abduction.’ No 

persuasive reasons are now presented to justify overruling this

line of cases. They [504 U.S. 655,662] rest on the sound basis 

that due process of law is satisfied when one present in court is 

convicted of crime after having been fairly apprized of the 

charges against him and after a fair trial in accordance with 

constitutional procedural safeguards. There is nothing in the 

Constitution that requires a court to permit a guilty person 

rightfully convicted to escape justice because he was brought to 

trial against his will.” Frisbie, supra, at 522 (citation and 

footnote omitted).

In construing a treaty, as in construing a statute, we first look to 

its terms to determine its meaning. ... The Treaty says nothing about 

the obligations of the United States and Mexico to refrain from 

forcible abductions of people from the territory of the other nation, or 

the consequences under the Treaty if such an abduction occurs....

More critical to respondent’s argument is Article 9 of the 

Treaty, which provides:

“1. Neither Contracting Party shall be bound to deliver 

up its own nationals, but the executive authority of the 

requested Party shall, if not prevented by the laws of that Party, 

have the power to deliver them up if, in its discretion, it be 

deemed proper to do so.

“2. If extradition is not granted pursuant to paragraph 1 

of this Article, the requested Party shall submit the case to its 

competent authorities for the purpose of prosecu- 

CHAPTER 9

JURISDICTION OF STATES

tion, provided that Party has jurisdiction over the offense.”

Id., at 5065. [504 US. 655, 664]

According to respondent, Article 9 embodies the terms of the 

bargain which the United States struck: If the United States wishes to 

prosecute a Mexican national, it may request that individual’s 

extradition. Upon a request from the United States, Mexico may 

either extradite the individual or submit the case to the proper 

authorities for prosecution in Mexico. In this way, respondent 

reasons, each nation preserved its right to choose whether its nationals 

would be tried in its own courts or by the courts of the other nation. 

This preservation of rights would be frustrated if either nation were 

free to abduct nationals of the other nation for the purposes of 

prosecution. More broadly, respondent reasons, as did the Court of 

Appeals, that all the processes and restrictions on the obligation to 

extradite established by the Treaty would make no sense if either 

nation were free to resort to forcible kidnapping to gain the presence 

of an individual for prosecution in a manner not contemplated by the 

Treaty. Verdugo, supra, at 1350.

We do not read the Treaty in such a fashion. Article 9 does not

purport to specify the only way in which one country may gain 

custody of a national of the other country for the purposes of 

prosecution. In the absence of an extradition treaty, nations are under

no obligation to surrender those in their country to foreign authorities 

for prosecution. Rauscher, 119 US., at 411-412; Factor v. 

Laubenheimer, 290 US. 276,287(1933); cf. Valentine v. United 

States ex rel. Neidecker, supra, at 8-9. (United States may not 

extradite a citizen in the absence of a statute or treaty obligation). 

Extradition treaties exist so as to impose mutual obligations to 

surrender individuals in certain defined sets of circumstances, 

following established procedures. See 1 J. Moore, A Treatise on 

Extradition and Interstate Rendition 72 (1891). The Treaty thus 

provides a mechanism which would not otherwise exist, requiring, 

under certain circumstances, the United States and Mexico to 

extradite individuals to the [504 U.S. 655, 665] other country and 

establishing the procedures to be followed when the Treaty is 

invoked.

The history of negotiation and practice under the Treaty also 

fails to show that abductions outside of the Treaty constitute a 

violation of the Treaty. As the Solicitor General notes, the Mexican 

Government was made aware, as early as 1906, of the Ker doctrine, 

and the United States’ position that it applied to forcible abductions 

made outside of the terms of the United States-Mexico

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Extradition Treaty. Nonetheless, the current version of the Treaty, 

signed in 1978, does not attempt to establish a rule that would in any 

way curtail the effect of Ker. Moreover, although language which 

would grant individuals exactly the right sought by respondent had 

been considered and drafted as early as 1935 by a prominent group of 

legal scholars sponsored by the faculty of Harvard Law School, no 

such clause appears in the current Treaty.

Thus, the language of the Treaty, in the context of its history, 

does not support the proposition that the Treaty prohibits abductions 

outside of its terms. The remaining question, therefore, is whether the 

Treaty should be interpreted so as to include an implied term 

prohibiting prosecution where the defendant’s presence is obtained by 

means other than those established by the Treaty. See Valentine, 299 

US., at 17 (“Strictly, the question is not whether there had been a 

uniform practical construction denying the power, but whether the 

power had been so clearly recognized that the grant should be 

implied.”)

Respondent contends that the Treaty must be interpreted against 

the backdrop of customary international law, and that international 

abductions are “so clearly prohibited in international law” that there 

was no reason to include such a clause in the Treaty itself. Brief for 

Respondent 11. The international censure of international abductions 

is further evidenced, according to respondent, by the United Nations 

Charter and the Charter of the Organization of American States. Id., at 

17. Respondent does not argue that these sources of international law 

provide an independent basis for the right respondent asserts not to be 

tried in the United States, but rather that they should inform the 

interpretation of the Treaty terms. [504 US. 655, 667]

The Court of Appeals deemed it essential, in order for the 

individual defendant to assert a right under the Treaty, that the affected 

foreign government had registered a protest. Verdugo, 939 F.2d, at 

1357 (“In the kidnapping case, there must be a formal protest from the 

offended government after the kidnapping”). Respondent agrees that 

the right exercised by the individual is derivative of the nation’s right 

under the Treaty, since nations are authorized, notwithstanding the 

terms of an extradition treaty, to voluntarily render an individual to the 

other country on terms completely outside of those provided in the 

treaty. The formal protest, therefore, ensures that the “offended” nation 

actually objects to the abduction, and has not in some way voluntarily 

rendered the individual for prosecution. Thus, the Extradition

CHAPTER 9

JURISDICTION OF STATES

179

Treaty only prohibits gaining the defendant’s presence by means other 

than those set forth in the Treaty when the nation from which the 

defendant was abducted objects.

This argument seems to us inconsistent with the remainder of 

respondent’s argument. The Extradition Treaty has the force of law, 

and if, as respondent asserts, it is self-executing, it would appear that a 

court must enforce it on behalf of an individual regardless of the 

offensiveness of the practice of one nation to the other nation. In 

Rauscher, the Court noted that Great Britain had taken the position in 

other cases that the Webster-Ashburton Treaty included the doctrine of 

specialty, but no importance was attached to whether or not Great 

Britain had protested the prosecution of Rauscher for the crime of cruel 

and unusual punishment, as opposed to murder.

More fundamentally, the difficulty with the support respondent 

gamers from international law is that none of it relates to the practice 

of nations in relation to extradition treaties. In Rauscher, we implied a 

term in the Webster-Ashburton Treaty because of the practice of 

nations with regard to extradition treaties. In the instant case, 

respondent [504 U.S. 655, 668] would imply terms in the Extradition 

Treaty from the practice of nations with regards to international law 

more generally. Respondent would have us find that the Treaty acts as 

a prohibition against a violation of the general principle of 

international law that one government may not “exercise its police 

power in the territory of another state.” Brief for Respondent 16. There 

are many actions which could be taken by a nation that would violate 

this principle, including waging war, but it cannot seriously be 

contended that an invasion of the United States by Mexico would 

violate the terms of the Extradition Treaty between the two nations.

In sum, to infer from this Treaty and its terms that it prohibits all 

means of gaining the presence of an individual [504 U.S. 655, 669] 

outside of its terms goes beyond established precedent and practice. In 

Rauscher, the implication of a doctrine of specialty into the terms of 

the Webster-Ashburton Treaty which, by its terms, required the 

presentation of evidence establishing probable cause of the crime of 

extradition before extradition was required, was a small step to take. 

By contrast, to imply from the terms of this Treaty that it prohibits 

obtaining the presence of an individual by means outside of the 

procedures the Treaty establishes requires a much larger inferential 

leap, with only the most general of international law principles to 

support it. The general principles

180 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

cited by respondent simply fail to persuade us that we should imply in 

the United States-Mexico Extradition Treaty a term prohibiting 

international abductions.

Respondent and his amici may be correct that respondent’s 

abduction was “shocking,” Tr. of Oral Arg. 40, and that it may be in 

violation of general international law principles. Mexico has protested 

the abduction of respondent through diplomatic notes,

App. 33-38, and the decision of whether respondent should be returned 

to Mexico, as a matter outside of the Treaty, is a matter for the 

Executive Branch. We conclude, however, that respondent’s abduction 

was not in violation of the Extradition Treaty between the United 

States and Mexico, and therefore the rule of Ker v. Illinois is fully 

applicable to this case. The fact of respondent’s forcible abduction 

does not therefore prohibit his trial in a court in the United States for 

violations of the criminal laws of the United States.

The judgment of the Court of Appeals is therefore reversed, and 

the case is remanded for further proceedings consistent with this 

opinion.

So ordered.

The following case illustrates how the due process requirements work in an 

extradition case:

SECRETARY OF JUSTICE vs. HON. RALPH C. LANTION G.R. No. 139465. 

October 17,2000

EN BANC (footnotes omitted)

The jugular issue is whether or not the private respondent is 

entitled to the due process right to notice and hearing during the 

evaluation stage of the extradition process.

We now hold that private respondent is bereft of the right to 

notice and hearing during the evaluation stage of the extradition 

process.

First. RD. No. 1069 which implements the RP-US Extradition 

Treaty provides the time when an extraditee shall be furnished a copy 

of the petition for extradition as well as its supporting papers,

i. e„ after the filing of the petition for extradition in the extradition 

court, viz.:

CHAPTER 9

JURISDICTION OF STATES

“SECTION 6. Issuance of Summons; Temporary Arrest; 

Hearing; Service of Notices. — (1) Immediately upon receipt of 

the petition, the presiding judge of the court shall, as soon as 

practicable, summon the accused to appear and to answer the 

petition on the day and hour fixed in the order. ... Upon receipt 

of the answer, or should the accused after having received the 

summons fail to answer within the time fixed, the presiding 

judge shall hear the case or set another date for the hearing 

thereof.

(2) The order and notice as well as a copy of the warrant 

of arrest, if issued, shall be promptly served each upon the 

accused and the attorney having charge of the case.”

It is of judicial notice that the summons includes the petition for 

extradition which will be answered by the extraditee.

There is no provision in the RP-US Extradition Treaty and in 

P.D. No. 1069 which gives an extraditee the right to demand from the 

petitioner Secretary of Justice copies of the extradition request from 

the US government and its supporting documents and to comment 

thereon while the request is still undergoing evaluation. We cannot 

write a provision in the treaty giving private respondent that right 

where there is none. It is well-settled that a “court cannot alter, amend, 

or add to a treaty by the insertion of any clause, small or great, or 

dispense with any of its conditions and requirements or take away any 

qualification, or integral part of any stipulation, upon any motion of 

equity, or general convenience, or substantial justice.”

Second. All treaties, including the RP-US Extradition Treaty, 

should be interpreted in light of their intent. Nothing less than the 

Vienna Convention on the Law of Treaties to which the Philippines is 

a signatory provides that “a treaty shall be interpreted in good faith in 

accordance with the ordinary meaning to be given to the terms of the 

treaty in their context and in light of its object and purpose.” (emphasis 

supplied) The preambular paragraphs of P.D. No. 1069 define its 

intent, viz.:

“WHEREAS, under the Constitution^] the Philippines 

adopts the generally accepted principles of international law as 

part of the law of the land, and adheres to the policy of peace, 

equality, justice, freedom, cooperation and amity with all 

nations;

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

WHEREAS, the suppression of crime is the concern not 

only of the state where it is committed but also of any other 

state to which the criminal may have escaped, because it saps

the foundation of social life and is an outrage upon humanity at 

large, and it is in the interest of civilized communities that 

crimes should not go unpunished;

WHEREAS, in recognition of this principle the 

Philippines recently concluded an extradition treaty with the 

Republic of Indonesia, and intends to conclude similar treaties 

with other interested countries; ...” (emphasis supplied)

It cannot be gainsaid that today, countries like the Philippines 

forge extradition treaties to arrest the dramatic rise of international and 

transnational crimes like terrorism and drug trafficking. Extradition 

treaties provide the assurance that the punishment of these crimes will 

not be frustrated by the frontiers of territorial sovereignty. Implicit in

the treaties should be the unbending commitment that the perpetrators 

of these crimes will not be coddled by any signatory state.

It ought to follow that the RP-US Extradition Treaty calls for an 

interpretation that will minimize if not prevent the escape of 

extraditees from the long arm of the law and expedite their trial. The 

submission of the private respondent, that as a probable extraditee 

under the RP-US Extradition Treaty he should be furnished a copy of 

the US government request for his extradition and its supporting 

documents even while they are still under evaluation by petitioner 

Secretary of Justice, does not meet this desideratum. The fear of the 

petitioner Secretary of Justice that the demanded notice is equivalent 

to a notice to flee must be deeply rooted on the experience of the 

executive branch of our government. As it comes from the branch of 

our government in charge of the faithful execution of our laws, it 

deserves the careful consideration of this Court. In addition, it cannot 

be gainsaid that private respondent’s demand for advance notice can 

delay the summary process of executive evaluation of the extradition 

request and its accompanying papers. The foresight of Justice Oliver 

Wendell Holmes did not miss this danger. In 1911, he held:

“It is common in extradition cases to attempt to bring to 

bear all the factitious niceties of a criminal trial at common law. 

But it is a waste of time ... if there is presented, even in 

somewhat untechnical form according to our ideas,

CHAPTER 9

JURISDICTION OF STATES

such reasonable ground to suppose him guilty as to make it

proper that he should be tried, good faith to the demanding

government requires his surrender.” (emphasis supplied)

We erode no right of an extraditee when we do not allow time to 

stand still on his prosecution. Justice is best served when done without 

delay.

Third. An equally compelling factor to consider is the understanding of the parties themselves to the RP-US Extradition Treaty as 

well as the general interpretation of the issue in question by other 

countries with similar treaties with the Philippines. The rule is 

recognized that while courts have the power to interpret treaties, the 

meaning given them by the departments of government particularly 

charged with their negotiation and enforcement is accorded great 

weight. The reason for the rule is laid down in Santos III v. Northwest 

Orient Airlines, et al., where we stressed that a treaty is a joint 

executive legislative act which enjoys the presumption that “it was first 

carefully studied and determined to be constitutional before it was 

adopted and given the force of law in the country.”

Our executive department of government, thru the Department 

of Foreign Affairs (DFA) and the Department of Justice (DOJ), has 

steadfastly maintained that the RP-US Extradition Treaty and P.D. No. 

1069 do not grant the private respondent a right to notice and hearing 

during the evaluation stage of an extradition process. This 

understanding of the treaty is shared by the US government, the other 

party to the treaty. This interpretation by the two governments cannot 

be given scant significance. It will be presumptuous for the Court to 

assume that both governments did not understand the terms of the 

treaty they concluded.

Yet, this is not all. Other countries with similar extradition 

treaties with the Philippines have expressed the same interpretation 

adopted by the Philippine and US governments. Canadian 11 and 

Hongkong authorities, thru appropriate note verbales communicated to 

our Department of Foreign Affairs, stated in unequivocal language that 

it is not an international practice to afford a potential extraditee with a 

copy of the extradition papers during the evaluation stage of the 

extradition process. We cannot disregard such a convergence of views 

unless it is manifestly erroneous.

Fourth. Private respondent, however, peddles the postulate that 

he must be afforded the right to notice and hearing as required by our 

Constitution. He buttresses his position by likening an

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

extradition proceeding to a criminal proceeding and the evaluation 

stage to a preliminary investigation.

We are not persuaded. An extradition proceeding is sui generis.

It is not a criminal proceeding which will call into operation all the 

rights of an accused as guaranteed by the Bill of Rights. To begin with, 

the process of extradition does not involve the determination of the 

guilt or innocence of an accused. His guilt or innocence will be 

adjudged in the court of the state where he will be extradited. Hence, 

as a rule, constitutional rights that are only relevant to determine the 

guilt or innocence of an accused cannot be invoked by an extraditee 

especially by one whose extradition papers are still undergoing 

evaluation. As held by the US Supreme Court in United States v. 

Galanis:

“An extradition proceeding is not a criminal prosecution, 

and the constitutional safeguards that accompany a criminal trial 

in this country do not shield an accused from extradition 

pursuant to a valid treaty.”

There are other differences between an extradition proceeding 

and a criminal proceeding. An extradition proceeding is summary in 

nature while criminal proceedings involve a full-blown trial. In 

contradistinction to a criminal proceeding, the rules of evidence in an 

extradition proceeding allow admission of evidence under less 

stringent standards. In terms of the quantum of evidence to be 

satisfied, a criminal case requires proof beyond reasonable doubt for 

conviction while a fugitive may be ordered extradited “upon showing 

of the existence of a prima facie case.” Finally, unlike in a criminal 

case where judgment becomes executory upon being rendered final, in 

an extradition proceeding, our courts may adjudge an individual 

extraditable but the President has the final discretion to extradite him. 

The United States adheres to a similar practice whereby the Secretary 

of State exercises wide discretion in balancing the equities of the case 

and the demands of the nation’s foreign relations before making the 

ultimate decision to extradite.

As an extradition proceeding is not criminal in character and the 

evaluation stage in an extradition proceeding is not akin to a 

preliminary investigation, the due process safeguards in the latter do 

not necessarily apply to the former. This we hold for the procedural 

due process required by a given set of circumstances “must begin with 

a determination of the precise nature of the government function 

involved as well as the private interest that has been affected by 

governmental action.” The concept of due process is

CHAPTER 9

JURISDICTION OF STATES

flexible for “not all situations calling for procedural safeguards call for 

the same kind of procedure.”

Fifth. Private respondent would also impress upon the Court the 

urgency of his right to notice and hearing considering the alleged threat 

to his liberty “which may be more priceless than life.” The supposed 

threat to private respondent’s liberty is perceived to come from several 

provisions of the RP-US Extradition Treaty and P.D. No. 1069 which 

allow provisional arrest and temporary detention.

We first deal with provisional arrest. The RP-US Extradition 

Treaty provides as follows:

“PROVISIONAL ARREST

1. In case of urgency, a Contracting Party may request 

the provisional arrest of the person sought pending presentation 

of the request for extradition. A request for provisional arrest 

may be transmitted through the diplomatic channel or directly 

between the Philippine Department of Justice and the United 

States Department of Justice.

2. The application for provisional arrest shall contain:

a) a description of the person sought;

b) the location of the person sought, if known;

c) a brief statement of the facts of the case, 

including, if possible, the time and location of the offense;

d) a description of the laws violated;

e) a statement of the existence of a warrant of 

arrest or finding of guilt or judgment of conviction against 

the person sought; and

f) a statement that a request for extradition for 

the person sought will follow.

3. The Requesting State shall be notified without 

delay of the disposition of its application and the reasons for any 

denial.

4. A person who is provisionally arrested may be 

discharged from custody upon the expiration of sixty (60)

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

days from the date of arrest pursuant to this Treaty if the 

executive authority of the Requested State has not received the 

formal request for extradition and the supporting documents 

required in Article 7.” (emphasis supplied)

In relation to the above, Section 20 of RD. No. 1069 provides:

“SECTION 20. Provisional Arrest. — (a) In case of 

urgency, the requesting state may, pursuant to the relevant treaty 

or convention and while the same remains in force, request for 

the provisional arrest of the accused, pending receipt of the 

request for extradition made in accordance with Section 4 of this 

Decree.

(b) A request for provisional arrest shall be sent to the 

Director of the National Bureau of Investigation, Manila, either 

through the diplomatic channels or direct by post or telegraph.

(c) The Director of the National Bureau of Investigation or any official acting on his behalf shall upon receipt of 

the request immediately secure a warrant for the provisional 

arrest of the accused from the presiding judge of the Court of 

First Instance of the province or city having jurisdiction of the 

place, who shall issue the warrant for the provisional arrest of 

the accused. The Director of the National Bureau of 

Investigation through the Secretary of Foreign Affairs shall 

inform the requesting state of the result of its request.

(d) If within a period of 20 days after the provisional 

arrest the Secretary of Foreign Affairs has not received the

request for extradition and the documents mentioned in Section 

4 of this Decree, the accused shall be released from custody.” 

(emphasis supplied)

Both the RP-US Extradition Treaty and P.D. No. 1069 clearly 

provide that private respondent may be provisionally arrested only 

pending receipt of the request for extradition. Our DFA has long 

received the extradition request from the United States and has turned 

it over to the DOJ. It is undisputed that until today, the United States 

has not requested for private respondent’s provisional arrest. 

Therefore, the threat to private respondent’s liberty has passed. It is 

more imagined than real.

CHAPTER 9

JURISDICTION OF STATES

Nor can the threat to private respondent’s liberty come from 

Section 6 of P.D. No. 1069, which provides:

“SECTION 6. Issuance of Summons; Temporary Arrest; 

Hearing, Service of Notices. — (1) Immediately upon receipt of 

the petition, the presiding judge of the court shall, as soon as 

practicable, summon the accused to appear and to answer the 

petition on the day and hour fixed in the order. [H]e may issue a 

warrant for the immediate arrest of the accused which may be 

served anywhere within the Philippines if it appears to the 

presiding judge that the immediate arrest and temporary 

detention of the accused will best serve the ends of justice.

(2) The order and notice as well as a copy of the warrant 

of arrest, if issued, shall be promptly served each upon the 

accused and the attorney having charge of the case.” (emphasis 

supplied)

It is evident from the above provision that a warrant of arrest for 

the temporary detention of the accused pending the extradition hearing 

may only be issued by the presiding judge of the extradition court 

upon filing of the petition for extradition. As the extradition process is 

still in the evaluation stage of pertinent documents and there is no 

certainty that a petition for extradition will be filed in the appropriate 

extradition court, the threat to private respondent’s liberty is merely 

hypothetical.

Sixth. To be sure, private respondent’s plea for due process 

deserves serious consideration involving as it does his primordial right 

to liberty. His plea to due process, however, collides with important 

state interests which cannot also be ignored for they serve the interest 

of the greater majority. The clash of rights demands a delicate 

balancing of interests approach which is a “fundamental postulate of 

constitutional law.” The approach requires that we “take conscious and 

detailed consideration of the interplay of interests observable in a 

given situation or type of situation.” These interests usually consist in 

the exercise by an individual of his basic freedoms on the one hand, 

and the government’s promotion of fundamental public interest or 

policy objectives on the other.

In the case at bar, on one end of the balancing pole is the private 

respondent’s claim to due process predicated on Section

1, Article III of the Constitution, which provides that “No person shall 

be deprived of life, liberty, or property without due process of law ...” 

Without a bubble of doubt, procedural due process of law

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

lies at the foundation of a civilized society which accords paramount 

importance to justice and fairness. It has to be accorded the weight it 

deserves.

This brings us to the other end of the balancing pole. Petitioner 

avers that the Court should give more weight to our national 

commitment under the RP-US Extradition Treaty to expedite the 

extradition to the United States of persons charged with violation of 

some of its laws. Petitioner also emphasizes the need to defer to the 

judgment of the Executive on matters relating to foreign affairs in 

order not to weaken if not violate the principle of separation of powers.

Considering that in the case at bar, the extradition proceeding is

only at its evaluation stage, the nature of the right being claimed by the 

private respondent is nebulous and the degree of prejudice he will 

allegedly suffer is weak, we accord greater weight to the interests 

espoused by the government thru the petitioner Secretary of Justice. In 

Angara v. Electoral Commission, we held that the “Constitution has 

blocked out with deft strokes and in bold lines, allotment of power to 

the executive, the legislative and the judicial departments of the 

government.” Under our constitutional scheme, executive power is 

vested in the President of the Philippines. Executive power includes, 

among others, the power to contract or guarantee foreign loans and the 

power to enter into treaties or international agreements. The task of 

safeguarding that these treaties are duly honored devolves upon the 

executive department which has the competence and authority to so act 

in the international arena. It is traditionally held that the President has 

power and even supremacy over the country’s foreign relations. The 

executive department is aptly accorded deference on matters of foreign 

relations considering the President’s most comprehensive and most 

confidential information about the international scene of which he is 

regularly briefed by our diplomatic and consular officials. His access 

to ultra-sensitive military intelligence data is also unlimited. The 

deference we give to the executive department is dictated by the 

principle of separation of powers. This principle is one of the 

cornerstones of our democratic government. It cannot be eroded 

without endangering our government.

The Philippines also has a national interest to help in 

suppressing crimes and one way to do it is to facilitate the extradition 

of persons covered by treaties duly entered by our government. More 

and more, crimes are becoming the concern of one world. Laws 

involving crimes and crime prevention are

CHAPTER 9

JURISDICTION OF STATES

undergoing universalization. One manifest purpose of this trend 

towards globalization is to deny easy refuge to a criminal whose 

activities threaten the peace and progress of civilized countries. It is to 

the great interest of the Philippines to be part of this irreversible 

movement in light of its vulnerability to crimes, especially 

transnational crimes.

In tilting the balance in favor of the interests of the State, the 

Court stresses that it is not ruling that the private respondent has no 

right to due process at all throughout the length and breadth of the 

extrajudicial proceedings. Procedural due process requires a 

determination of what process is due, when it is due, and the degree of 

what is due. Stated otherwise, a prior determination should be made as 

to whether procedural protections are at all due and when they are due, 

which in turn depends on the extent to which an individual will be 

“condemned to suffer grievous loss.” We have explained why an 

extraditee has no right to notice and hearing during the evaluation 

stage of the extradition process. As aforesaid, P.D. No. 1069 which 

implements the RP-US Extradition Treaty affords an extraditee 

sufficient opportunity to meet the evidence against him once the 

petition is filed in court. The time for the extraditee to know the basis 

of the request for his extradition is merely moved to the filing in court 

of the formal petition for extradition. The extraditee’s right to know is 

momentarily withheld during the evaluation stage of the extradition 

process to accommodate the more compelling interest of the State to 

prevent escape of potential extraditees which can be precipitated by 

premature information of the basis of the request for his extradition. 

No less compelling at that stage of the extradition proceedings is the 

need to be more deferential to the judgment of a co-equal branch of the 

government, the Executive, which has been endowed by our 

Constitution with greater power over matters involving our foreign 

relations. Needless to state, this balance of interests is not a static but a 

moving balance which can be adjusted as the extradition process 

moves from the administrative stage to the judicial stage and to the 

execution stage depending on factors that will come into play. In sum, 

we rule that the temporary hold on private respondent’s privilege of 

notice and hearing is a soft restraint on his right to due process which 

will not deprive him of fundamental fairness should he decide to resist 

the request for his extradition to the United States. There is no denial 

of due process as long as fundamental fairness is assured a party.

We end where we began. A myopic interpretation of the due 

process clause would not suffice to resolve the conflicting rights in

190 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

the case at bar. With the global village shrinking at a rapid pace, 

propelled as it is by technological leaps in transportation and communication, we need to push further back our horizons and work with 

the rest of the civilized nations and move closer to the universal goals 

of “peace, equality, justice, freedom, cooperation and amity with all 

nations.” In the end, it is the individual who will reap the harvest of 

peace and prosperity from these efforts.

WHEREFORE, the Urgent Motion for Reconsideration is 

GRANTED. The Decision in the case at bar promulgated on January

18, 2000 is REVERSED. The assailed Order issued by the public 

respondent judge on August 9, 1999 is SET ASIDE.

The temporary restraining order issued by this Court on August 17,

1999 is made PERMANENT. The Regional Trial Court of Manila, 

Branch 25 is enjoined from conducting further proceedings in Civil 

Case No. 99-94684.

Bail in extradition cases

If after his arrest and if the trial court finds that an extraditee is not a flight 

risk, the court may grant him bail. (In this case the grant of bail presupposed that a 

co-petitioner, the wife, had already presented evidence to prove her right to be on 

bail, that she was no flight risk, and the trial court had already exercised its sound 

discretion and had already determined that under the Constitution and laws in force, 

co- petitioner was entitled to provisional release.) The Court emphasized that bail 

may be granted to a possible extraditee only upon a clear and convincing showing 

(1) that he will not be a flight risk or a danger to the community, and (2) that there 

exist special, humanitarian and compelling circumstances.6

In a later case, the Court said that it could not ignore the following trends in 

international law: (1) the growing importance of the individual person in public 

international law who, in the 20th century, has gradually attained global 

recognition; (2) the higher value now being given to human rights in the 

international sphere; (3) the corresponding duty of countries to observe these 

universal human rights in fulfilling their treaty obligations; and (4) the duty of the 

Court to balance the rights of the individual under our fundamental law, on one 

hand, and the law on extradition, on the other. It added, “If bail can be granted in 

deportation

cases, we see no justification why it should not also be allowed in extradition cases. 

After all, both are administrative proceedings where the innocence or guilt of the 

person detained is not in issue.”7

The decision departs from the earlier case of Mark Jimenez (US v. Judge 

Puruganan, September 24, 2002) which said that bail is not available in extradition 

cases.

’Gov’t of Hongkong v. Olalia, GR 153675, April 19,2007.

Chapter 10 IMMUNITY FROM JURISDICTION

Immunity from jurisdiction.

The general rule is that the jurisdiction of a state within its territory is 

complete and absolute. However, there are two categories of exceptions to this rule. 

The first is sovereign immunity and the second is the immunity of the 

representative of states or diplomatic and consular immunities. Sovereign immunity 

covers both a head of state and the state itself.

Immunity of head of state.

Immunity from jurisdiction is enjoyed by both the head of state and by the 

state itself. The example many authors give of the immunity of a head of state is the 

case of Mighell v. Sultan ofJohore.' The Sultan of Johore was sued for breach of 

promise to marry in a British court. The subject of the suit therefore was a private 

matter, not a state matter. Upon verification of his being a sitting foreign sovereign, 

the case was dismissed. The immunity that is recognized here is absolute for a 

sitting head of state.

More recent is the Pinochet Case which involved one who no longer was a 

head of state but whose immunity for official or governmental acts was recognized.

The Pinochet Case: Background

General Augusto Pinochet led a 1973 military coup that overthrew 

democratically-elected Chilean President Salvador Allende. According to a national 

truth and reconciliation commission, at least 3,196 people

'1 QB 148(1894).

192

CHAPTER 10

IMMUNITY FROM JURISDICTION

were killed or forcibly disappeared during Pinochet’s subsequent 17- year 

dictatorship. Thousands more were tortured or exiled.

On October 16, 1998, while seeking medical help in London, British 

authorities detained Augusto Pinochet on an arrest warrant issued by Spanish 

Magistrate Baltasar Garzon. Garzon who had charged Pinochet with genocide, 

terrorism, and torture committed during the Chilean dictatorship and was seeking 

his extradition.

In November 1998, a panel of British law lords ruled that Pinochet did not 

enjoy immunity from prosecution as a former head of state and could be extradited 

to Spain. This decision, based largely on customary international law, was set aside, 

however, when one of the judges who heard the appeal was found to have ties to 

Amnesty International. A larger panel of law lords heard the appeal again in March 

1999, and in a 6-1 decision, reaffirmed that Pinochet could be extradited.

REGINA v. BARTLE AND THE COMMISSIONER OF POLICE

ON 24 March 1999 House of Lords

LORD BROWNE-WILKINSON

. . . [i]n my judgment, Senator Pinochet as former head of state 

enjoys immunity ratione materiae in relation to acts done by him as 

head of state as part of his official functions as head of state.

The question then which has to be answered is whether the 

alleged organisation of state torture by Senator Pinochet (if proved) 

would constitute an act committed by Senator Pinochet as part of his 

official functions as head of state....

Can it be said that the commission of a crime which is an 

international crime against humanity and jus cogens is an act done in 

an official capacity on behalf of the state? I believe there to be strong 

ground for saying that the implementation of torture as defined by the 

Torture Convention cannot be a state function. This is the view taken 

by Sir Arthur Watts (supra) who said (at p. 82):

“The idea that individuals who commit international 

crimes are internationally accountable for them has now become 

an accepted part of international law. Problems in this area — 

such as the non-existence of any standing

194 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

international tribunal to have jurisdiction over such crimes, and 

the lack of agreement as to what acts are internationally criminal 

for this purpose— have not affected the general acceptance of 

the principle of individual responsibility for international 

criminal conduct.”

Later, at p. 84, he said:

“It can no longer be doubted that as a matter of general 

customary international law a head of state will personally be 

liable to be called to account if there is sufficient evidence that 

he authorized or perpetrated such serious international crimes.”

Finally, and to my mind decisively, if the implementation of a torture regime 

is a public function giving rise to immunity ratione materiae, this produces bizarre 

results. Immunity ratione materiae applies not only to ex-heads of state and exambassadors but to all state officials who have been involved in carrying out the 

functions of the state. Such immunity is necessary in order to prevent state

immunity being circumvented by prosecuting or suing the official who, for 

example, actually carried out the torture when a claim against the head of state 

would be precluded by the doctrine of immunity. If that applied to the present case, 

and if the implementation of the torture regime is to be treated as official business 

sufficient to found an immunity for the former head of state, it must also be official 

business sufficient to justify immunity for his inferiors who actually did the 

torturing. Under the [Torture] Convention the international crime of torture can 

only be committed by an official or someone in an official capacity. They would all 

be entitled to immunity.... Therefore, the whole elaborate structure of universal 

jurisdiction over torture committed by officials is rendered abortive and one of the 

main objectives of the Torture Convention — to provide a system under which 

there is no safe haven for torturers — will have been frustrated. In my judgment, all 

these factors together demonstrate that the notion of continued immunity for exheads of state is inconsistent with the provisions of the Torture Convention.

For these reasons in my judgment if, as alleged, Senator Pinochet organized 

and authorized torture after 8 December 1988, he was not acting in any capacity 

which gives rise to immunity ratione materiae because such actions were contrary 

to international law ...

CHAPTER 10

IMMUNITY FROM JURISDICTION

195

[The Chilean government and other extradition opponents then 

urged the British government to send the former dictator back to Chile 

on medical grounds. Despite the protests of legal and medical experts 

from several countries, British Home Secretary Jack Straw released 

Pinochet on March 2,2000, ostensibly on health grounds.]

State immunity.

The principle that the state may not be sued without its consent found in the 

Philippine Constitution is both municipal law and also international law applicable 

to foreign states. This is based on the principle of equality of states: par in parent 

non habet imperium.

An early case, The Schooner Exchange v. MacFaddon1

is usually cited as 

authority for saying that states enjoy absolute immunity. Chief Justice Marshall 

noted that “the nation within its own territory is necessarily exclusive and absolute. 

It is susceptible of no limitation not imposed by itself.” However, he immediately 

added that absolute territorial jurisdiction “would not seem to contemplate foreign 

sovereigns nor their sovereign rights as its objects. One sovereign being in no 

respect amenable to another; and being bound by obligations of the highest 

character not to degrade the dignity of his nation, by placing himself or its 

sovereign rights within the jurisdiction of another, can be supposed to enter a 

foreign territory ... in the confidence that the immunities belonging to his 

independent sovereign station, though not expressly stipulated, are reserved by 

implication, and will be extended to him.”

The immunity of the sovereign head is seen as also communicated to the 

sovereign state: “This perfect equality and absolute independence of sovereigns, 

and this common interest impelling them to mutual intercourse, and an interchange 

of good offices with each other, have given rise to a class of cases in which every 

sovereign is understood to waive the exercise of a part of that complete exclusive 

territorial jurisdiction, which has been stated to be the attribute of every nation.”

With the gradual expansion of state involvement in commerce, the principle 

evolved over the years. Immunity came to be reserved only for acts jure imperii

(governmental acts) but not for acts jure gestionis

2

11 U.S. 116 [Cranch],

196 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

(trading and commercial acts). Dralle v. Republic of Czechoslovakia,3

after a 

survey of various jurisdictions concluded:

The Supreme Court therefore reaches the conclusion that it can 

no longer be said that by international law so-called acta gestionis are 

exempt from municipal jurisdiction. This subjection of the acta 

gestionis to the jurisdiction of States has its basis in the development of 

the commercial activity of States.

The classic doctrine of immunity arose at a time when all their political 

activities, either by the purchase of commodities for their diplomatic 

representatives abroad, or by the purchase of war material for war 

purposes, etc. Therefore, there was no justification for any distinction 

between private transactions and acts of sovereignty. Today the 

position is entirely different;

States engage in commercial activities and, as the present case shows, 

enter into competition with their own nationals and with foreigners. 

Accordingly, the classic doctrine of immunity has lost its meaning and, 

ratione cessante, can no longer be recognized as a rule of international 

law.

This rule is also followed in Philippine jurisdiction as shown especially by 

the numerous cases involving U.S. military bases authorities. United States of 

America v. Hon. V.M. Ruiz* categorically said:

The traditional rule of State immunity exempts a State from 

being sued in the courts of another State without its consent or waiver. 

This rule is a necessary consequence of the principles of independence 

and equality of States. However, the rules of International Law are not 

petrified; they are constantly developing and evolving. And because 

the activities of states have multiplied, it has been necessary to 

distinguish them — between sovereign and governmental acts (jure 

imperii) and private, commercial and proprietary acts (jure gestionis).

The result is that State immunity now extends only to acts jure imperii.

The restrictive application of State immunity is now the rule in the 

United States, the United Kingdom and other states in western Europe.

The restrictive application of State immunity is proper only

when the proceedings arise out of commercial transactions of the 

foreign sovereign, its commercial activities or economic affairs. Stated 

differently, a State may be said to have descended to the level of an 

individual and can thus be deemed to have tacitly given

S

CHAPTER 10

IMMUNITY FROM JURISDICTION

197

its consent to be sued only when it enters into business contracts.

It does not apply where the contract relates to the exercise of its 

sovereign functions. In this case, the projects [repairs of base facilities] 

are an integral part of the naval base which is devoted to the defense of 

both the United States and the Philippines, indisputably a function of 

the government of the highest order; they are not utilized for nor 

dedicated to commercial or business purposes.

In United States v. Hon. Luis Reyes,5

the claim of immunity was rejected 

when it was shown that the acts of the American official were committed not only 

outside the scope of her authority but also contrary to law:

It is a different matter where the public official is made to 

account in his capacity as such for acts contrary to law and injurious to 

the rights of plaintiff. ... ‘Inasmuch as the State authorizes only legal 

acts by its officers, unauthorized acts of government officials or 

officers are not acts of the State, and an action against the officials or 

officers by one whose rights have been invaded or violated by such 

acts, for the protection of his rights, is not a suit against the State 

within the rule of immunity of the State from suit.

In the same tenor, it has been said that an action at law or suit in equity 

against a State officer or the director of a State department on the 

ground that, while claiming to act for the State, he violates or invades 

the personal and property rights or the plaintiff, under an 

unconstitutional act or under an assumption of authority which he does 

not have, is not a suit against the State within the constitutional 

provision that the State may not be sued without its consent.’

The rationale for this ruling is that the doctrine of state immunity 

cannot be used as an instrument for perpetrating an injustice.

In the Holy See v. Eriberto Rosario, Jr.,6 where it was claimed that the Holy 

See had waived its sovereign immunity by entering into a contract for the sale of a 

piece of land, the Court said:

In the absence of legislation defining what activities and 

transactions shall be considered “commercial” and as constituting acts 

jure gestionis, we have to come out with our own guidelines, tentative

they may be.

Certainly, the mere entering into a contract by a foreign state 

with a private party cannot be the ultimate test. Such an act can

5G.R. No. 79253, March 1,1993.

6G.R. No. 101949, December 

198 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

only be the start of the inquiry. The logical question is whether the 

foreign state is engaged in the activity in the regular course of 

business. If the foreign state is not engaged regularly in a business or 

trade, the particular act or transaction must then be tested by its nature. 

If the act is in pursuit of a sovereign activity, or an incident thereof, 

then it is an act jure imperii, especially when it is not undertaken for 

gain or profit.

In the case at bench, if petitioner has bought and sold lands in 

the ordinary course of a real estate business, surely the said transaction 

can be categorized as an act jure gestionis. However, petitioner has 

denied that the acquisition and subsequent disposal of Lot 5-A were 

made for profit but claimed that it acquired said property for the site of 

its mission or the Apostolic Nunciature in the Philippines. Private 

respondent failed to dispute said claim.

The Court also indicated how a state claiming sovereign immunity should 

proceed:

In Public International Law, when a state or international 

agency wishes to plead sovereign or diplomatic immunity in a foreign 

court, it requests the Foreign Office of the state where it is sued to 

convey to the court that said defendant is entitled to immunity.

In the Philippines, the practice is for the foreign government or 

the international organization to first secure an executive endorsement 

of its claim of sovereign or diplomatic immunity. But how the 

Philippine Foreign Office conveys its endorsement to the courts varies.

By way of consolation, however, the Court added: “Private respondent is not 

left without any legal remedy for the redress of its grievances. Under both Public 

International Law and Transnational Law, a person who feels aggrieved by the acts 

of a foreign sovereign can ask his own government to espouse his cause through 

diplomatic channels.”

REPUBLIC OF INDONESIA V. VINZON G S.. No. 154705, June 26,2003

AZCUNA, J.:

Petitioner, Republic of Indonesia, represented by its Counsellor, 

Siti Partinah, entered into a Maintenance Agreement in August 1995 

with respondent James Vinzon, sole proprietor of

CHAPTER 10

IMMUNITY FROM JURISDICTION

Vinzon Trade and Services. The Maintenance Agreement stated that 

respondent shall, for a consideration, maintain specified equipment at 

the Embassy Main Building, Embassy Annex Building and the Wisma 

Duta, the official residence of petitioner Ambassador Soeratmin. The 

equipment covered by the Maintenance Agreement are air 

conditioning units, generator sets, electrical facilities, water heaters, 

and water motor pumps. It is likewise stated therein that the agreement 

shall be effective for a period of four years and will renew itself 

automatically unless cancelled by either party by giving thirty days 

prior written notice from the date of expiry.

Petitioners claim that sometime prior to the date of expiration of 

the said agreement, or before August 1999, they informed respondent 

that the renewal of the agreement shall be at the discretion of the 

incoming Chief of Administration, Minister Counsellor Azhari Kasim, 

who was expected to arrive in February 2000. When Minister 

Counsellor Kasim assumed the position of Chief of Administration in 

March 2000, he allegedly found respondent’s work and services 

unsatisfactory and not in compliance with the standards set in the 

Maintenance Agreement. Hence, the Indonesian Embassy terminated 

the agreement in a letter dated August 31, 2000. Petitioners claim, 

moreover, that they had earlier verbally informed respondent of their 

decision to terminate the agreement.

On the other hand, respondent claims that the aforesaid 

termination was arbitrary and unlawful. Respondent cites various 

circumstances which purportedly negated petitioners’ alleged 

dissatisfaction over respondent’s services: (a) in July 2000, Minister 

Counsellor Kasim still requested respondent to assign to the embassy 

an additional full-time worker to assist one of his other workers; (b) in 

August 2000, Minister Counsellor Kasim asked respondent to donate a 

prize, which the latter did, on the occasion of the Indonesian 

Independence Day golf tournament; and (c) in a letter dated August 22, 

2000, petitioner Ambassador Soeratmin thanked respondent for 

sponsoring a prize and expressed his hope that the cordial relations 

happily existing between them will continue to prosper and be 

strengthened in the coming years.

Hence, on December 15,2000, respondent filed a complaint 

against petitioners docketed as Civil Case No. 18203 in the Regional 

Trial Court (RTC) of Makati, Branch 145. On February 20, 2001, 

petitioners filed a Motion to Dismiss, alleging that the Republic of 

Indonesia, as a foreign sovereign State, has sovereign immunity from 

suit and cannot be sued as a party-defendant in the Philippines. The 

said motion further alleged that Ambassador

200 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Soeratmin and Minister Counsellor Kasim are diplomatic agents as 

defined under the Vienna Convention on Diplomatic Relations and 

therefore enjoy diplomatic immunity. In turn, respondent filed on 

March 20, 2001, an Opposition to the said motion alleging that the 

Republic of Indonesia has expressly waived its immunity from suit. 

He based this claim upon the following provision in the Maintenance 

Agreement:

“Any legal action arising out of this Maintenance

Agreement shall be settled according to the laws of the Philippines and by the proper court of Makati City, Philippines.”

Respondent’s Opposition likewise alleged that Ambassador 

Soeratmin and Minister Counsellor Kasim can be sued and held liable 

in their private capacities for tortious acts done with malice and bad 

faith.

On May 17, 2001, the trial court denied herein petitioners’ 

Motion to Dismiss. It likewise denied the Motion for Reconsideration 

subsequently filed.

The trial court’s denial of the Motion to Dismiss was brought up 

to the Court of Appeals by herein petitioners in a petition for 

certiorari and prohibition. Said petition, docketed as CA-G.R. SP No. 

66894, alleged that the trial court gravely abused its discretion in 

ruling that the Republic of Indonesia gave its consent to be sued and 

voluntarily submitted itself to the laws and jurisdiction of Philippine 

courts and that petitioners Ambassador Soeratmin and Minister 

Counsellor Kasim waived their immunity from suit.

On May 30,2002, the Court of Appeals rendered its assailed 

decision denying the petition for lack of merit. On August 16, 2002, it

denied herein petitioners’ motion for reconsideration.

Hence, this petition.

In the case at bar, petitioners raise the sole issue of whether or 

not the Court of Appeals erred in sustaining the trial court’s decision 

that petitioners have waived their immunity from suit by using as its

basis the above-mentioned provision in the Maintenance Agreement.

The petition is impressed with merit.

International law is founded largely upon the principles of 

reciprocity, comity, independence, and equality of States which were 

adopted as part of the law of our land under Article II, Section 2 of the 

1987 Constitution. The rule that a State may not be sued

CHAPTER 10

IMMUNITY FROM JURISDICTION

without its consent is a necessary consequence of the principles of 

independence and equality of States. [United States of America, et al. v. 

Ruiz, 136 SCRA 487 (1987).] As enunciated in Sanders v. Veridiano 

II, 162 SCRA 88, 96 (1988), the practical justification for the doctrine 

of sovereign immunity is that there can be no legal right against the 

authority that makes the law on which the right depends. In the case of 

foreign States, the rule is derived from the principle of the sovereign 

equality of States, as expressed in the maxim par in parem non habet 

imperium. All states are sovereign equals and cannot assert jurisdiction 

over one another. A contrary attitude would “unduly vex the peace of 

nations.”

The rules of International Law, however, are neither unyielding 

nor impervious to change. The increasing need of sovereign States to 

enter into purely commercial activities remotely connected with the 

discharge of their governmental functions brought about a new 

concept of sovereign immunity. This concept, the restrictive theory, 

holds that the immunity of the sovereign is recognized only with 

regard to public acts or acts jure imperii, but not with regard to private 

acts or acts jure gestionis. [The Holy See v. Rosario, et al., 238 SCRA

524 (1994)].

In United States v. Ruiz, for instance, we held that the conduct of 

public bidding for the repair of a wharf at a United States Naval 

Station is an act jure imperii. On the other hand, we considered as an 

act jure gestionis the hiring of a cook in the recreation center catering 

to American servicemen and the general public at the John Hay Air 

Station in Baguio City, United States v. Rodrigo, 182 SCRA 644 

(1990), as well as the bidding for the operation of barber shops in 

Clark Air Base in Angeles City.

Apropos the present case, the mere entering into a contract by a 

foreign State with a private party cannot be construed as the ultimate 

test of whether or not it is an act jure imperii or jure gestionis. Such act 

is only the start of the inquiry. Is the foreign State engaged in the 

regular conduct of a business? If the foreign State is not engaged 

regularly in a business or commercial activity, and in this case it has 

not been shown to be so engaged, the particular act or transaction must 

then be tested by its nature. If the act is in pursuit of a sovereign 

activity, or an incident thereof, then it is an act jure imperii.

Hence, the existence alone, of a paragraph in a contract stating 

that any legal action arising out of the agreement shall be settled 

according to the laws of the Philippines and by a specified court of

202 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

the Philippines is not necessarily a waiver of sovereign immunity from 

suit. The aforesaid provision contains language not necessarily 

inconsistent with sovereign immunity. On the other hand, such 

provision may also be meant to apply where the sovereign party elects 

to sue in the local courts, or otherwise waives its immunity by any 

subsequent act. The applicability of Philippine laws must be deemed to 

include Philippine laws in its totality, including the principle 

recognizing sovereign immunity. Hence, the proper court may have no 

proper action, by way of settling the case, except to dismiss it.

Submission by a foreign state to local jurisdiction must be clear 

and unequivocal. It must be given explicitly or by necessary 

implication. We find no such waiver in this case.

Respondent concedes that the establishment of a diplomatic 

mission is a sovereign function. On the other hand, he argues that the

actual physical maintenance of the premises of the diplomatic mission, 

such as the upkeep of its furnishings and equipment, is no longer a 

sovereign function of the State.

We disagree. There is no dispute that the establishment of a 

diplomatic mission is an act jure imperii. A sovereign State does not 

merely establish a diplomatic mission and leave it at that; the 

establishment of a diplomatic mission encompasses its maintenance 

and upkeep. Hence, the State may enter into contracts with private 

entities to maintain the premises, furnishings and equipment of the 

embassy and the living quarters of its agents and officials. It is 

therefore clear that petitioner Republic of Indonesia was acting in 

pursuit of a sovereign activity when it entered into a contract with 

respondent for the upkeep or maintenance of the air conditioning units, 

generator sets, electrical facilities, water heaters, and water motor 

pumps of the Indonesian Embassy and the official residence of the 

Indonesian ambassador.

The Solicitor General, in his Comment, submits the view that, 

“the Maintenance Agreement was entered into by the Republic of 

Indonesia in the discharge of its governmental functions. In such a 

case, it cannot be deemed to have waived its immunity from suit.” As 

to the paragraph in the agreement relied upon by respondent, the 

Solicitor General states that it “was not a waiver of their immunity 

from suit but a mere stipulation that in the event they do waive their 

immunity, Philippine laws shall govern the resolution of any legal 

action arising out of the agreement and the proper court in Makati City 

shall be the agreed venue thereof.

CHAPTER 10

IMMUNITY FROM JURISDICTION

203

On the matter of whether or not petitioners Ambassador 

Soeratmin and Minister Counsellor Kasim may be sued herein in their 

private capacities, Article 31 of the Vienna Convention on Diplomatic 

Relations provides:

xxx xxx xxx

1. A diplomatic agent shall enjoy immunity from the 

criminal jurisdiction of the receiving State. He shall also enjoy immunity from its civil and administrative jurisdiction, except in the case 

of:

(a) a real action relating to private immovable property 

situated in the territory of the receiving State, unless he holds it 

on behalf of the sending State for the purposes of the mission;

(b) an action relating to succession in which the 

diplomatic agent is involved as executor, administrator, heir or 

legatee as a private person and not on behalf of the sending 

State;

(c) an action relating to any professional or 

commercial activity exercised by the diplomatic agent in the 

receiving State outside his official functions.

xxx xxx xxx

The act of petitioners Ambassador Soeratmin and Minister 

Counsellor Kasim in terminating the Maintenance Agreement is not 

covered by the exceptions provided in the abovementioned provision.

The Solicitor General believes that said act may fall under 

subparagraph (c) thereof, but said provision clearly applies only to a 

situation where the diplomatic agent engages in any professional or 

commercial activity outside official functions, which is not the case 

herein.

WHEREFORE, the petition is hereby GRANTED.

Diplomatic and consular immunities.

The law governing diplomatic relations dates back to earliest intercourse 

between nations. Much of it is customary law. Official representatives of a state are 

given immunities and privileges when they are within the territory of another state. 

The immunities and privileges they enjoy are personal in the sense that they benefit 

the person. But the purpose of the immunities given them is functional, that is, to 

enable

204 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

them to perform their functions properly. On the part of the receiving state there lie 

certain obligations to protect the representative and his property and office. The law 

on this subject is very important because of the reliance states place on their 

representatives in dealing with other states.

Diplomatic immunities.

Diplomats are concerned with the political relations of states. The 

codification of the law on the subject may be found in the Vienna Convention on 

Diplomatic Relations (1961). The diplomatic representatives who can enjoy 

immunities in varying degrees are enumerated in Article I;

Article I

For the purpose of the present Convention, the following 

expressions shall have the meanings hereunder assigned to them:

(a) the "head of the mission ” is the person charged by the 

sending State with the duty of acting in that capacity;

(b) the “members of the mission” are the head of the mission 

and the members of the staff of the mission;

(c) the “members of the staff of the mission ” are the members of the diplomatic staff, of the administrative and technical staff 

and of the service staff of the mission;

(d) the “members of the diplomatic staff" are the members of 

the staff of the mission having diplomatic rank;

(e) a “diplomatic agent" is the head of the mission or a 

member of the diplomatic staff of the mission;

(f) the “members of the administrative and technical staff"

are the members of the staff of the mission employed in the 

administrative and technical service of the mission;

(g) the “members of the service staff" are the members of the 

staff of the mission in the domestic service of the mission;

(h) a “private servant” is a person who is in the domestic 

service of a member of the mission and who is not an employee of the 

sending State;

(i) the “premises of the mission" are the buildings or parts of 

buildings and the land ancillary thereto, irrespective of ownership, 

used for the purposes of the mission including the residence of the 

head of the mission.

CHAPTER 10

IMMUNITY FROM JURISDICTION

205

The functions of the diplomatic mission are enumerated in Article 3:

(a) representing the sending State in the receiving State;

(b) protecting in the receiving State the interests of the sending State 

and of its nationals, within the limits permitted by international law; (c) 

negotiating with the Government of the receiving State;

(d) ascertaining by all lawful means conditions and developments in 

the receiving State, and reporting thereon to the Government of the 

sending State; (e) promoting friendly relations between the sending 

State and the receiving State, and developing their economic, cultural 

and scientific relations.

Diplomatic relations between states are purely by mutual consent. Before the 

head of mission is sent to the receiving state, an agreement must first be obtained. 

The receiving state is under no obligation to give reasons for refusing an agreement. 

(Art. 4) Moreover, the “receiving State may at any time, and without having to 

explain its decision, notify the sending State that the head of the mission or any 

member of the diplomatic staff of the mission is persona non grata or that any 

other member of the staff of the mission is not acceptable. In any such case, the 

sending State shall, as appropriate, either recall the person concerned or terminate 

his functions with the mission. A person may be declared non grata or not 

acceptable before arriving in the territory of the receiving State.” (Art. 9).

The following are some of the rights and privileges of the diplomatic 

mission:

Article 22

1. The premises of the mission shall be inviolable. The 

agents of the receiving State may not enter them, except with the 

consent of the head of the mission.

2. The receiving State is under a special duty to take all 

appropriate steps to protect the premises of the mission against any 

intrusion or damage and to prevent any disturbance of the peace of the 

mission or impairment of its dignity.

3. The premises of the mission, their furnishings and other 

property thereon and the means of transport of the mission shall be 

immune from search, requisition, attachment or execution.

206 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Article 23

1. The sending State and the head of the mission shall be 

exempt from all national, regional or municipal dues and taxes in 

respect of the premises of the mission, whether owned or leased, other 

than such as represent payment for specific services rendered.

2. The exemption from taxation referred to in this Article 

shall not apply to such dues and taxes payable under the law of the

head of the mission.

Article 24

The archives and documents of the mission shall be inviolable 

at any time and wherever they may be.

Article 27

employ all appropriate means, including diplomatic couriers and 

messages in code or cipher. However, the mission may install and use 

a wireless transmitter only with the consent of the receiving State.

inviolable. Official correspondence means all correspondence relating

State in the performance of his functions. He shall enjoy personal 

inviolability and shall not be liable to any form of arrest or detention.

6. The sending State or the mission may designate diplomatic 

couriers ad hoc. In such cases the provisions of paragraph 5 of this 

Article shall also apply, except that the immunities therein

CHAPTER 10

IMMUNITY FROM JURISDICTION

207

mentioned shall cease to apply when such a courier has delivered to 

the consignee the diplomatic bag in his charge.

7. A diplomatic bag may be entrusted to the captain of a 

commercial aircraft scheduled to land at an authorized port of entry. 

He shall be provided with an official document indicating the number 

of packages constituting the bag but he shall not be considered to be a 

diplomatic courier. The mission may send one of its members to take

possession of the diplomatic bag directly and freely from the captain of 

the aircraft.

Article 29

The person of a diplomatic agent shall be inviolable. He shall 

not be liable to any form of arrest or detention. The receiving State

Article 31

1. A diplomatic agent shall enjoy immunity from the criminal 

jurisdiction of the receiving State. He shall also enjoy immunity from 

its civil and administrative jurisdiction, except in the case of:

(a) a real action relating to private immovable property

on behalf of the sending State for the purposes of the mission; 

(b) an action relating to succession in which the diplomatic 

agent is involved as executor, administrator, heir or legatee as a

measures concerned can be taken without infringing the inviolability 

of his person or of his residence.

of the receiving State does not exempt him from the jurisdiction of the 

sending State.

Article 32

1. The immunity from jurisdiction of diplomatic agents and 

of persons enjoying immunity under Article 37 may be waived by the 

sending State.

2. Waiver must always be express.

3. The initiation of proceedings by a diplomatic agent or by 

a person enjoying immunity from jurisdiction under Article 37 shall 

preclude him from invoking immunity from jurisdiction in respect of 

any counter-claim directly connected with the principal claim.

or administrative proceedings shall not be held to imply waiver of 

immunity in respect of the execution of the judgment, for which a

conducted only in the presence of the diplomatic agent or of his 

authorized representative.

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Article 37

1. The members of the family of a diplomatic agent forming 

part of his household shall, if they are not nationals of the receiving 

State, enjoy the privileges and immunities specified in Articles 29 to 

36.

2. Members of the administrative and technical staff of the 

mission, together with members of their families forming part of their 

respective households, shall, if they are not nationals of or 

permanently resident in the receiving State, enjoy the privileges and 

immunities specified in Articles 29 to 35, except that the immunity 

from civil and administrative jurisdiction of the receiving State 

specified in paragraph 1 of Article 31 shall not extend to acts 

performed outside the course of their duties. They shall also enjoy the 

privileges specified in Article 36, paragraph 1, in respect of articles 

imported at the time of first installation.

3. Members of the service staff of the mission who are not 

nationals of or permanently resident in the receiving State shall enjoy 

immunity in respect of acts performed in the course of their duties, 

exemption from dues and taxes on the emoluments they receive by 

reason of their employment and the exemption contained in Article 33.

4. Private servants of members of the mission shall, if they 

are not nationals of or permanently resident in the receiving State, be 

exempt from dues and taxes on the emoluments they receive by reason 

of their employment. In other respects, they may enjoy privileges and 

immunities only to the extent admitted by the receiving State. 

However, the receiving State must exercise its jurisdiction over those 

persons in such a manner as not to interfere unduly with the 

performance of the functions of the mission.

Article 38

1. Except insofar as additional privileges and immunities 

may be granted by the receiving State, a diplomatic agent who is a 

national of or permanently resident in that State shall enjoy only 

immunity from jurisdiction, and inviolability, in respect of official acts 

performed in the exercise of his functions.

2. Other members of the staff of the mission and private 

servants who are nationals of or permanently resident in the receiving 

State shall enjoy privileges and immunities only to the extent admitted 

by the receiving State. However, the receiving

CHAPTER 10

IMMUNITY FROM JURISDICTION

211

State must exercise its jurisdiction over those persons in such a manner 

as not to interfere unduly with the performance of the functions of the 

mission.

Article 39

1. Every person entitled to privileges and immunities shall

enjoy them from the moment he enters the territory of the receiving 

State on proceeding to take up his post or, if already in its territory, 

from the moment when his appointment is notified to the Ministry for 

Foreign Affairs or such other ministry as may be agreed.

2. When the functions of a person enjoying privileges and 

immunities have come to an end, such privileges and immunities shall 

normally cease at the moment when he leaves the country, or on expiry

of a reasonable period in which to do so, but shall subsist until that 

time, even in case of armed conflict. However, with respect to acts 

performed by such a person in the exercise of his functions as a 

member of the mission, immunity shall continue to subsist.

Finally, “it is the duty of all persons enjoying such privileges and immunities 

to respect the laws and regulations of the receiving state.” (Art. 41) Nor may they 

“practice for personal profit any professional or commercial activity” in the 

receiving state. (Art. 42)

Consuls and consular immunities.

Consuls are not concerned with political matters. They attend rather to 

administrative and economic issues such as the issuance of visas.

The codification of the law on consular relations may be found in the Vienna

Convention on Consular Relations which entered into force in 1967. Some of the 

more important provisions are the following:

Article 5. CONSULAR FUNCTIONS

Consular functions consist in:

(a) protecting in the receiving State the interests of the 

sending State and of its nationals, both individuals and bodies corporate, within the limits permitted by international law;

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

(b) furthering the development of commercial, economic, 

cultural and scientific relations between the sending State and the 

receiving State and otherwise promoting friendly relations between 

them in accordance with the provisions of the present Convention;

(c) ascertaining by all lawful means conditions and developments in the commercial, economic, cultural and scientific life of 

the receiving State, reporting thereon to the Government of the 

sending State and giving information to persons interested;

(d) issuing passports and travel documents to nationals of the 

sending State, and visas or appropriate documents to persons wishing 

to travel to the sending State;

(e) helping and assisting nationals, both individuals and

similar kind, and performing certain functions of an administrative 

nature, provided that there is nothing contrary thereto in the laws and 

regulations of the receiving State;

(g) safeguarding the interests of nationals, both individuals 

and bodies corporate, of the sending State in cases of succession 

mortis causa in the territory of the receiving State, in accordance with 

the laws and regulations of the receiving State;

(h) safeguarding, within the limits imposed by the laws and 

regulations of the receiving State, the interests of minors and other 

persons lacking full capacity who are nationals of the sending State,

receiving State, representing or arranging appropriate representation 

for nationals of the sending State before the tribunals and other 

authorities of the receiving State, for the purpose of obtaining, in

accordance with the laws and regulations of the receiving State, 

provisional measures for the preservation of the rights and interests of 

these nationals, where, because of absence or any other reason, such 

nationals are unable at the proper time to assume the defence of their 

rights and interests;

(j) transmitting judicial and extrajudicial documents or 

executing letters rogatory or commissions to take evidence for the

CHAPTER 10

IMMUNITY FROM JURISDICTION

213

any other manner compatible with the laws and regulations of the 

receiving State;

(k) exercising rights of supervision and inspection provided for 

in the laws and regulations of the sending State in respect of vessels 

having the nationality of the sending State, and of aircraft registered in 

that State, and in respect of their crews;

(1) extending assistance to vessels and aircraft mentioned in 

sub-paragraph (k) of this Article and to their crews, taking statements 

regarding the voyage of a vessel, examining and stamping the ship’s 

papers, and, without prejudice to the powers of the authorities of the 

receiving State, conducting investigations into any incidents which 

occurred during the voyage, and settling disputes of any kind between 

the master, the officers and the seamen in so far as this may be

authorized by the laws and regulations of the sending State;

(m) performing any other functions entrusted to a consular post 

by the sending State which are not prohibited by the laws and 

regulations of the receiving State or to which no objection is taken by 

the receiving State or which are referred to in the international 

agreements in force between the sending State and the receiving State.

The head of a consular post is admitted to the exercise of his functions by an 

authorization from the receiving State termed an exequatur. There is no prescribed 

form, but without it, he may not enter upon his duties. The receiving State may at 

any time notify the sending State that a consular officer is persona non grata or that 

any other member of the consular staff is not acceptable. In that event, the sending 

State shall, as the case may be, either recall the person concerned or terminate his 

functions with the consular post.

The receiving state has the duty to protect the consular premises, archives and 

interests of the sending state. (Arts. 27, 31, 32, 33) The receiving state must insure 

the unimpeded functioning of the consular offices.

Article 34. FREEDOM OF MOVEMENT

Subject to its laws and regulations concerning zones entry into 

which is prohibited or regulated for reasons of national

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

security, the receiving State shall ensure freedom of movement and 

travel in its territory to all members of the consular post.

Article 35. FREEDOM OF COMMUNICATION

1. The receiving State shall permit and protect freedom of 

communication on the part of the consular post for all official 

purposes. In communicating with the Government, the diplomatic 

missions and other consular posts, wherever situated, of the sending 

State, the consular post may employ all appropriate means, including 

diplomatic or consular couriers, diplomatic or consular bags and 

messages in code or cipher. However, the consular post may install 

and use a wireless transmitter only with the consent of the receiving 

State.

2. The official correspondence of the consular post shall be 

inviolable.

Official correspondence means all correspondence relating to 

the consular post and its functions.

3. The consular bag shall be neither opened nor detained. 

Nevertheless, if the competent authorities of the receiving State have 

serious reason to believe that the bag contains something other than 

the correspondence, documents or articles referred to in paragraph 4 of 

this Article, they may request that the bag be opened in their presence 

by an authorized representative of the sending State. If this request is 

refused by the authorities of the sending State, the bag shall be 

returned to its place of origin.

4. The packages constituting the consular bag shall bear 

visible external marks of their character and may contain only official 

correspondence and documents or articles intended exclusively for 

official use.

Article 36. COMMUNICATION AND CONTACT WITH NATIONALS OF THE SENDING STATE

1. With a view to facilitating the exercise of consular functions relating to nationals of the sending State:

(a) consular officers shall be free to communicate with 

nationals of the sending State and to have access to them. 

Nationals of the sending State shall have the same freedom with 

respect to communication with and access to consular officers 

of the sending State; (b) if he so requests,

CHAPTER 10

IMMUNITY FROM JURISDICTION

the competent authorities of the receiving State shall, without 

delay, inform the consular post of the sending State if, within its 

consular district, a national of that State is arrested or committed 

to prison or to custody pending trial or is detained in any other 

manner. Any communication addressed to the consular post by 

the person arrested, in prison, custody or detention shall also be 

forwarded by the said authorities without delay. The said 

authorities shall inform the person concerned without delay of 

his rights under this sub-paragraph; (c) consular officers shall 

have the right to visit a national of the sending State who is in 

prison, custody or detention, to converse and correspond with 

him and to arrange for his legal representation. They shall also 

have the right to visit any national of the sending State who is in 

prison, custody or detention in their district in pursuance of a 

judgment. Nevertheless, consular officers shall refrain from taking action on behalf of a national who is in prison, custody or 

detention if he expressly opposes such action.

Article 41. PERSONAL INVIOLABILITY OF CONSULAR 

OFFICERS

1. Consular officers shall not be liable to arrest or deten

tion pending trial, except in the case of a grave crime and pursuant to a 

decision by the competent judicial authority.

Article 42. NOTIFICATION OF ARREST, DETENTION OR 

PROSECUTION

In the event of the arrest or detention, pending trial, of a member 

of the consular staff, or of criminal proceedings being instituted against 

him, the receiving State shall promptly notify the head of the consular 

post.

Article 43. IMMUNITY FROM JURISDICTION

1. Consular officers and consular employees shall not be 

amenable to the jurisdiction of the judicial or administrative authorities 

of the receiving State in respect of acts performed in the exercise of 

consular functions.

2. The provisions of paragraph 1 of this Article shall not, 

however, apply in respect of a civil action either:

216 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

(a) arising out of a contract concluded by a consular 

officer or a consular employee in which he did not contract 

expressly or impliedly as an agent of the sending State; or

(b) by a third party for damage arising from an accident in the 

receiving State caused by a vehicle, vessel or aircraft.

Article 44. LIABILITY TO GIVE EVIDENCE

1. Members of a consular post may be called upon to attend as 

witnesses in the course of judicial or administrative proceedings. A 

consular employee or a member of the service staff shall not, except in 

the cases mentioned in paragraph 3 of this Article, decline to give 

evidence. If a consular officer should decline to do so, no coercive 

measure or penalty may be applied to him.

Article 45. WAIVER OF PRIVILEGES AND IMMUNITIES

1. The sending State may waive, with regard to a member of 

the consular post, any of the privileges and immunities provided for in 

Articles 41,43 and 44.

Diplomatic and consular immunities were the subject in the case of United 

States v. Tehran:

US DIPLOMATIC AND CONSULAR STAFF IN IRAN CASE

United States v. Tehran ICJ Rep 1980 3

On 4 November 1979, Iranian students seized the US 

Embassy in Tehran and a number of consulates in outlying 

cities. The Iranian authorities failed to protect the Embassy and 

later appeared to adopt the students’ actions. Over 50 US 

nationals (mostly diplomatic and consular staff) were held for 

444 days. The ICJ had indicated provisional measures against 

Iran (ICJ Rep 1979 7), and in this case the US sought a 

declaration, inter alia, that Iran had violated the two Vienna 

Conventions, and calling for the release of the hostages and the 

vacation of the Embassy and consulates. The Court considered 

whether the initial attack by the students could be attributed to 

the Iranian Government and whether Iran was therefore in 

violation of its international obligations.

CHAPTER 10

IMMUNITY FROM JURISDICTION

68. The Court is therefore led inevitably to conclude, in 

regard to the first phase of the events which has so far been considered, 

that on 4 November 1979, the Iranian authorities:

(a) were fully aware of their obligations under the 

conventions in force to take appropriate steps to protect the 

premises of the United States Embassy and its diplomatic and 

consular staff from any attack and from any infringement of 

their inviolability, and to ensure the security of such other 

persons as might be present on the said premises;

(b) were fully aware, as a result of the appeals for help 

made by the United States Embassy, of the urgent need for 

action on their part;

(c) had the means at their disposal to perform their 

obligations;

(d) completely failed to comply with these obligations.

Similarly, the Court is led to conclude that the Iranian 

authorities were equally aware of their obligations to protect the 

United States Consulates at Tabriz and Shiraz, and of the need for 

action on their part, and similarly failed to use the means which were 

at their disposal to comply with their obligations.

69. The second phase of the events which are the subject of 

the United States’ claims comprises the whole series of facts which 

occurred following the completion of the occupation of the United 

States Embassy by the militants, and the seizure of the Consulates at 

Tabriz and Shiraz. The occupation having taken place and the 

diplomatic and consular personnel of the United States’ mission 

having been taken hostages, the action required of the Iranian 

Government by the Vienna Conventions and by general international 

law manifest. Its plain duty was at once to make every effort, and to 

take every appropriate step, to bring these flagrant infringements of the 

inviolability of the premises, archives and diplomatic and consular 

staff of the United States Embassy to a speedy end, to restore the 

Consulates at Tabriz and Shiraz to United States control, and in 

general to re-establish the status quo and to offer reparation for the 

damage.

76. The Iranian authorities’ decision to continue the subjection 

of the premises of the United States Embassy to occupation by 

militants and of the Embassy staff to detention as hostages, clearly 

gave rise to repeated and multiple breaches of the applica

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

ble provisions of the Vienna Conventions even more serious than 

those which arose from their failure to take any steps to prevent the 

attacks on the inviolability of these premises and staff.

87. In the present case, the Iranian Government did not break 

off diplomatic relations with the United States; and in response to a 

question put to him by a Member of the Court, the United States 

Agent informed the Court that at no time before the events of 4 

November 1979 had the Iranian Government declared, or indicated 

any intention to declare, any member of the United States diplomatic 

or consular staff in Tehran persona non grata. The Iranian 

Government did not, therefore, employ the remedies placed at its 

disposal by diplomatic law specifically for dealing with activities of 

the kind of which it now complains. Instead, it allowed a group of 

militants to attack and occupy the United States Embassy by force, 

and to seize the diplomatic and consular staff as hostages; instead, it 

has endorsed that action of those militants and has deliberately 

maintained their occupation of the Embassy and detention of its staff 

as a means of coercing the sending State. It has, at the same time, 

refused altogether to discuss this situation with representatives of the 

United States. The Court, therefore, can only conclude that Iran did 

not have recourse to the normal and efficacious means at its disposal, 

but resorted to coeicive action against the United States Embassy and 

its staff.

92. It is a matter of deep regret that the situation which 

occasioned those observations has not been rectified since they were 

made. Having regard to their importance the Court considers it 

essential to reiterate them in the present Judgment. The frequency with 

which at the present time the principles of international law governing 

diplomatic and consular relations are set at naught by individuals or 

groups of individuals is already deplorable. But this case is unique and 

of very particular gravity because here it is not only private individuals 

or groups of individuals that have disregarded and set at naught the 

inviolability of a foreign embassy, but the government of the receiving 

State itself. Therefore, in recalling yet again the extreme importance of 

the principles of law which it is called upon to apply in the present 

case, the Court considers it to be its duty to draw the attention of the 

entire international community, of which Iran itself has been a 

member since time immemorial, to the irreparable harm that may be 

caused

by events of the kind now before the Court. Such events cannot fail to 

undermine the edifice of law carefully constructed by mankind over a 

period of centuries, the maintenance of which is vital for the security 

and well-being of the complex international community of the present 

day, to which it is more essential than ever that the rules developed to 

ensure the ordered progress of relations between its members should 

be constantly and scrupulously respected.

The Act of State Doctrine.

The act of state doctrine arose from a series of cases in the United States 

where the issue was whether United States courts could consider the validity of acts 

of a foreign state alleged to be in violation of international law. The doctrine was 

first stated in Underhill v. Hernandez.1

The background of the case was a 1892 revolution in Venezuela against the 

legitimate government. General Hernandez commanded the anti-administration

party and, after defeating the army of the administration, he entered Bolivar to 

assume leadership of the government. George F. Underhill was a citizen of the 

United States who had constructed a waterworks system for the city of Bolivar, 

under a contract with the government, and was engaged in supplying the place with 

water. He also carried on a machinery repair business. Some time after the entry of 

Gen. Hernandez, Underhill applied to him for a passport to leave the city. 

Hernandez refused this request as well as requests made by others in Underhill’s 

behalf. The purpose of Hernandez’s refusal was to coerce Underhill to operate his 

waterworks and his repair works for the benefit of the community and the 

revolutionary forces. After Underhill was finally allowed to leave, he filed suit in 

the United States to recover damages for the detention caused by reason of the 

denial of his permit to leave, for his alleged confinement to his own house, and for 

certain alleged assaults and affronts by the soldiers of Hernandez’s army. In 

denying the plea of Underhill, the U.S. court ruled with what is now known as the 

“act of state doctrine”:

7

168 U.S. 250 (1897), November 29,1897.

220 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Every sovereign state is bound to respect the independence of 

every other sovereign state, and the courts of one country will not sit in 

judgment on the acts of the government of another, done within its 

own territory. Redress of grievances by reason of such acts must be 

obtained through the means open to be availed of by sovereign powers 

as between themselves.

The doctrine is similar to but different from the doctrine of sovereign 

immunity. What underlies it was explained later in Banco National de Cuba v. 

Sabbatinos which characterized it as a rule not of international law but of judicial 

restraint in domestic law whereby courts refrain from making decisions in 

deference to the executive who is the principal architect of foreign relations. The 

Court said:

The act of state doctrine does, however, have “constitutional” 

underpinnings. It arises out of the basic relationships between branches 

of government in a system of separation of powers. It concerns the 

competency of dissimilar institutions to make and implement 

particular kinds of decisions in the area of international relations. The 

doctrine as formulated in past decisions expresses the strong sense of 

the Judicial Branch that its engagement in the task of passing on the 

validity of foreign acts of state may hinder rather than further this 

country’s pursuit of goals both for itself and for the community of 

nations as a whole in the international sphere....

The act of state doctrine was again taken up in Alfred Dunhill of London, 

Inc. v. Cuba.9

The issue in the case was whether the failure of Cuba to return to 

Dunhill funds mistakenly paid by Dunhill for cigars that had been sold to Dunhill 

by certain expropriated Cuban cigar businesses was an “act of state” by Cuba 

precluding an affirmative judgment against respondents. The decision of the Court 

limited the scope of the act of state doctrine:

If we assume with the Court of Appeals that the Cuban 

Government itself had purported to exercise sovereign power to 

confiscate the mistaken payments belonging to three foreign creditors 

and to repudiate interventors’ adjudicated obligation to return those 

funds, we are nevertheless persuaded by the arguments of petitioner 

and by those of the United States that the concept of

*

3

7

CHAPTER 10

IMMUNITY FROM JURISDICTION

221

an act of state should not be extended to include the repudiation of a 

purely commercial obligation owed by a foreign sovereign or by one 

of its commercial instrumentalities. Our cases have not yet gone so far, 

and we decline to expand their reach to the extent necessary to affirm 

the Court of Appeals.

sjc $ $ $ *

Of course, sovereign immunity has not been pleaded in this 

case; but it is beyond cavil that part of the foreign relations law 

recognized by the United States is that the commercial obligations of a 

foreign government may be adjudicated in those courts otherwise 

having jurisdiction to enter such judgments. Nothing in our national 

policy calls on us to recognize as an act of state a repudiation by Cuba 

of an obligation adjudicated in our courts and arising out of the 

operation of a commercial business by one of its instrumentalities. ...

Further refinement was made in Kirkpatrick Co. v. Environmental Tectonics 

Corp.'0

The case had for background a contract entered into between the Nigerian 

government with Kirkpatrick for the construction and equipment of an aeromedical 

center at Kaduna Air Force Base in Nigeria. Environmental Tectonics Corporation, 

an unsuccessful bidder for the Kaduna contract, learned that Kirkpatrick had bribed 

Nigerian officals in winning the contract. Environmental Tectonics brought the 

matter to the attention of the Nigerian Air Force and to the United States Embassy

in Lagos. Following an investigation by the Federal Bureau of Investigation, the 

United States Attorney for the District of New Jersey brought charges against 

Kirkpatrick for violations of the Foreign Corrupt Practices Act of 1977. Kirkpatrick 

pleaded guilty. Whereupon, Environmental Tectonics brought a civil action against

Kirkpatrick and other private parties involved in the bribery to seek damages under 

the Racketeer Influenced and Corrupt Organizations Act and other statutes. The 

defendants moved to dismiss the complaint on the ground that the action was 

barred by the act of state doctrine.

When the case reached the Supreme Court, the Court ruled that the act of 

state doctrine is not applicable where the validity of a foreign government act is not 

in issue:

l0493 U.S. 400,410 (1990).

222 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The short of the matter is this: Courts in the United States have 

the power, and ordinarily the obligation, to decide cases and 

controversies properly presented to them. The act of state doctrine 

does not establish an exception for cases and controversies that may 

embarrass foreign governments, but merely requires that, in the 

process of deciding, the acts of foreign sovereigns taken within their 

own jurisdictions shall be deemed valid. That doctrine has no 

application to the present case because the validity of a foreign 

sovereign act is not at issue.

Chapter 11 STATE RESPONSIBILITY

In traditional international law, individuals are generally considered “objects” 

and not “subjects” of international law. They possess neither international legal 

rights which they could assert on their own. Whatever wrongs may be committed 

against them can be redressed only by states or organizations with international 

personality. Individuals, therefore, can be objects of state vs. state litigation. Out of 

this situation there have arisen doctrines regarding the protection of individuals and 

the responsibility of states for injuries inflicted on individuals. State responsibility 

for the ill-treatment of aliens is a common form of responsibility that arises in 

international law. This chapter will deal with the doctrine on the protection of aliens 

and on the still evolving subject of state responsibility.

Protection of Aliens.

No state is obliged to admit aliens into its territory unless there is a treaty 

requiring it. This principle is an aspect of sovereignty. Realistically, however, it is 

difficult to deny admission to all. Thus, what states generally do is to impose legal 

standards for admission. Once admitted, at least under democratic regimes, aliens 

may not be expelled without due process.

From the perspective of the state of their nationality, aliens are “nationals 

abroad.” They, therefore remain important for the state of their nationality. Hence, 

states do have a common interest in the protection of aliens. The practice of the 

proper treatment of aliens is based on this commonality of interest. States protect 

aliens within their jurisdiction in the expectation that their own nationals will be 

properly treated when residing or sojourning abroad. In fact, mistreatment of aliens 

is a common cause of international responsibility.

223

224 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Ill-treatment of foreign nationals can come in various forms, e.g., 

mistreatment by judicial or police authorities, unlawful expropriation of property, 

failure to prosecute those who attack foreign nationals, or what is called “denial of 

justice” or denial of due process of law.

There is a well-developed customary law for the protection of aliens. The 

instrument used for the protection of aliens is “diplomatic protection.” This is still 

based on the traditional notion that the individual is an inappropriate subject of 

international law and hence must have recourse to his or her state of nationality for 

protection. The theory underlying the system is that injury to a national abroad is 

injury to the individual’s state of nationality. The interest of the state is in the

redress of the injury to itself and not of the injury to the individual. Individuals, 

therefore, are at the mercy of their own state. States enjoy discretion whether or not 

to espouse claims raised by individuals in their own behalf. States might see their 

own sovereign interests as overriding whatever private interests their nationals 

might have. Moreover, as indicated in the Nottebohm case in Chapter 8, in the case 

of persons holding dual nationality, an “effective national link” with the person 

must exist for a state’s interest in an individual to be recognized by other states.

Corporations and Shareholders

The doctrine of “effective link” as applied to corporations received treatment 

in the Barcelona Traction Case.' The claim, which was brought before the Court 

on 19 June 1962, arose out of the adjudication in bankruptcy in Spain of Barcelona 

Traction, a company incorporated in Canada. The claim’s object was to seek 

reparation for damage alleged by Belgium to have been sustained by Belgian 

nationals, shareholders in the company, as a result of acts said to be contrary to 

international law committed towards the company by organs of the Spanish State.

The Court found that Belgium lacked jus standi to exercise diplomatic 

protection of shareholders in a Canadian company with respect to measures taken 

against that company in Spain. It observed that when a State admits into its territory 

foreign investments or foreign nationals it is bound to extend to them the protection 

of the law and to assume obligations concerning the treatment to be afforded them. 

But such obligations are not absolute. In order to bring a claim in respect

'Belgium v. Spain, (1970) ICJ Rep. 

CHAPTER 11

STATE RESPONSIBILITY

225

of the breach of such an obligation, a State must first establish its right to do so.

The breach, if any, was committed in this case against the company. Only the 

company, which was endowed with legal personality, could take action in respect of 

matters that were of a corporate character. It may be true that a wrong done to the 

company frequently causes prejudice to its shareholders; but this does not imply 

that both are entitled to claim compensation. Whenever a shareholder’s interests are 

harmed by an act done to the company, it is to the latter that he has to look to 

institute appropriate action. An act infringing only the company’s rights do not 

involve responsibility towards the shareholders, even if their interests are affected. 

In order for the situation to be different, the act complained of must be aimed at the

direct rights of the shareholder as such, which was not the case here.

As to who should have the right to protect the corporation, Barcelona 

Traction says that it is the state of nationality of the corporation, in this case 

Canada, which has the right, and not Belgium.

Standard for the Protection of Aliens

What is the international standard for the protection of aliens? International 

law has gone a long way from ancient times when aliens were treated as “outlaws” 

not deserving protection. Roman law progressed from this under the concept of jus 

gentium, which was applicable to both citizens and aliens, as distinct from jus civile

which was applicable only to Roman citizens. The advent of Christianity further 

improved the condition of aliens. The rights of aliens expanded further with the 

growth of international commerce in modem times leading to development of the 

concept of “denial of justice” as an international concern.

Two standards have emerged in modem times to compete for recognition as 

the acceptable standard. The first is what is called the doctrine of “national 

treatment” or “equality of treatment.” Aliens are treated in the same manner as 

nationals of the state where they reside. There is a bright side and a dark side to this 

doctrine. The bright side is that aliens would enjoy the same benefits as local 

nationals. The dark side is that, if the state is tyrannical and its municipal laws are 

harsh and violative of human rights even of its own citizens, then aliens would 

likewise be subject to such harsh laws.

226 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The other standard is called the “minimum international standard” which 

says that, however harsh the municipal laws might be against a state’s own citizens, 

aliens should be protected by certain minimum standards of humane protection. 

This is now the widely accepted standard.

The “minimum standard” is obviously abstract and it is not easy to 

determine what its contents are. An elaboration of this abstract standard may be 

seen in a quotation from the resolution of the Neer Claim? Mr. Neer was a US 

national working in Mexico. He was stopped by armed men and shot to death. It 

was claimed that the Mexican government had been negligent in their investigation 

of the murder. This was rejected by the Joint Claims Commission saying:

. . . [w]ithout attempting to announce a precise formula, it is in 

the opinion of the Commission possible to hold (first) that the 

propriety of the government acts should be put to the tests of 

international standards, and (second) that the treatment of an alien, in 

order to constitute an international delinquency should amount to an 

outrage, to bad faith, to willful neglect of duty, or to an insufficiency 

of governmental action so far short of international standards that 

every reasonable and impartial man would readily recognize its 

insufficiency. Whether the insufficiency proceeds from deficient 

execution of an intelligent law or from the fact that the laws of the 

country do not empower the authorities to measure up to international 

standards is immaterial.

The Harvard Draft Convention on the Responsibility of States for Damages

puts it in terms of the more limited concept of “denial of justice.”

Article 9. Denial of justice exists when there is a denial, 

unwarranted delay or obstruction of access to courts, gross deficiency 

in the administration of judicial or remedial process, failure to provide 

those guarantees which are generally considered indispensable to the 

proper administration of justice, or a manifestly unjust judgment. An 

error of a national court which does not produce manifest injustice is 

not denial of justice.

2United States v. Mexico, 4 RIAA (1926).

CHAPTER 11

STATE RESPONSIBILITY

227

Enforcement Regimes

The International Court of Justice, when its jurisdiction is appealed to by 

states in conflict, can resolve issues of violations of the rights of aliens. However, 

claims may also be settled by ad hoc tribunals established for the purpose. 

Examples are the US-Iran Claims Tribunal established by the US and Iran to deal 

with claims of either party arising from the Islamic Revolution; the UN 

Compensation Commission established by the Security Council in 1991 to deal 

with claims arising from Iraq’s invasion of Kuwait. States may also enter into lump 

sum settlements such as the US-Cambodia (1994) and US-Vietnam (1995) Claims 

Settlement Agreements.

Doctrine of State Responsibility.

The customary law doctrine on the protection of aliens should be seen in 

relation to the doctrine on “state responsibility.” When an injury has been inflicted, 

there is need to determine whether the state can be held responsible for it. One of 

the principles most strongly held by states is that if a state violates a customary rule 

of international law or a treaty obligation, it commits an “internationally wrongful 

act.” The International Law Commission for some years now has been working on 

the codification of the law on the subject. At its fifty-third session (2001), the 

International Law Commission adopted on second reading a complete text of the 

Articles on Responsibility of States for Internationally Wrongful Acts. The Articles 

have been referred to the General Assembly for consideration.

Although its work has not yet been finalized, much of what it has done so far 

consists of principles which are widely accepted. What need to be understood are: 

(1) the elements of an internationally wrongful act; (2) the attributability of the 

wrongful act to the state; and (3) the enforcement of the obligation that arises from 

the wrongful act. Excerpts from the 2001 Draft of the International Law 

Commission will be used as handy guide.

Internationally wrongful act.

Article 1. Responsibility of a State for its internationally 

wrongful acts

Every internationally wrongful act of a State entails the 

international responsibility of that State.

228 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

States derive immense benefits from the international legal system. 

Accordingly, when a state consents to be a part of that system, it also accepts 

corresponding legal obligations. Primarily, it must accept responsibility for actions 

which have an effect on other international legal persons. This is basically what 

Article 1 says. No state can escape this responsibility when once it has committed 

an act which satisfies the requirements of an “internationally wrongful act.”

Article 2. Elements of an internationally wrongful act of a

State

There is an internationally wrongful act of a State when conduct 

consisting of an action or omission:

(a) Is attributable to the State under international law; and

(b) Constitutes a breach of an international obligation of the 

State.

Article 3. Characterization of an act of a State as internationally 

wrongful

The characterization of an act of a State as internationally 

wrongful is governed by international law. Such characterization is not 

affected by the characterization of the same act as lawful by internal 

law.

Article 12. Breach of an international obligation

There is a breach of an international obligation by a State when 

an act of that State is not in conformity with what is required of it by 

that obligation, regardless of its origin or character.

Article 2 says that that the elements of an internationally wrongful act consist 

of a subjective and an objective element. The subjective element is that the act must 

be attributable not to the persons or agencies who performed it but to the state 

itself. The objective element is a violation of an international obligation. It may 

consist of something either active (action) or passive (an omission.)

Articles 3 and 12 say that what determines the wrongful character of the act 

is international law and not internal law. The international law violated can be 

customary or conventional.

Attribution to the State.

The acts which can be attributed to the state may be acts of state organs, the 

acts of other persons, or the acts of revolutionaries.

CHAPTER 11

STATE RESPONSIBILITY

229

Acts of state organs

Article 4. Attribution to the State of the conduct of its organs

1. For the purposes of the present articles, the conduct of any 

State organ acting in that capacity shall be considered an act of that 

State under international law, whether the organ exercises legislative, 

executive, judicial or any other functions, whatever position it holds in 

the organization of the State, and whatever its character as an organ of 

the central government or of a territorial unit of the State.

2. For the purposes of paragraph 1, an organ includes any 

person or body which has that status in accordance with the internal 

law of the State.

Article 5. Attribution to the State of the conduct of entities 

exercising elements of the governmental authority.

The conduct of an entity which is not an organ of the State under 

Article 4 but which is empowered by the law of that State to exercise 

elements of the governmental authority shall be considered an act of 

the State under international law, provided the entity was acting in that 

capacity in the case in question.

Article 6. Attribution to the State of conduct in fact carried out 

on its instructions or under its direction or control.

The conduct of a person or group of persons shall be considered 

an act of the State under international law if the person or group of 

persons was in fact acting on the instructions of, or under the direction 

or control of, that State in carrying out the conduct.

Article 7. Attribution to the State of certain conduct carried out 

in the absence of the official authorities

The conduct of a person or group of persons shall be considered 

an act of the State under international law if the person or group of 

persons was in fact exercising elements of the governmental authority 

in the absence or default of the official authorities and in circumstances 

such as to call for the exercise of those elements of authority.

Article 8. Attribution to the State of the conduct of organs 

placed at its disposal by another State

The conduct of an organ placed at the disposal of a State by 

another State shall be considered an act of the former State under

230 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

international law if the organ was acting in the exercise of elements of 

the governmental authority of the State at whose disposal it had been 

placed.

Article 9. Attribution to the State of the conduct of organs acting 

outside their authority or contrary to instructions.

The conduct of an organ of a State or of an entity empowered to 

exercise elements of the governmental authority, such organ or entity 

having acted in that capacity, shall be considered an act of the State 

under international law even if, in the particular case, the organ or 

entity exceeded its authority or contravened instructions concerning its 

exercise.

CAIRE CLAIM

France v. Mexico (1929)

French-Mexican Claims Commission

[Caire, a French national, was killed in Mexico by Mexican 

soldiers after they had demanded money from him.]

Verzijl, Presiding Commissioner

(4) Responsibility of Mexico for actions of individual military 

personnel, acting without orders or against the wishes of their 

commanding officers and independently of the needs and aims of the 

revolution...

In approaching the examination of the questions indicated under 

4 in the light of the general principles I have just outlined, I should like 

to make clear first of all that I am interpreting the said principles in 

accordance with the doctrine of the “objective responsibility” of the 

States, that is, the responsibility for the acts of the officials or organs

of a State, which may devolve upon it even in the absence of any 

“fault” of its own. It is widely known that theoretical conceptions in 

this sphere have advanced a great deal in recent times, and that the 

innovating work of Dionisio Anzilotti in particular has paved the way 

for new ideas, which no longer rank the responsibility of the State for 

the acts of its officials as subordinate to the question of the “fault” 

attaching to the State itself. Without going into the question of whether 

these new ideas, which are perhaps too absolute, may require some 

modifications in the direction proposed by Dr. Karl Strupp, I can say 

that I regard them as perfectly correct in that they tend to impute to the 

State, in international affairs, the responsibility for all the acts 

committed by its officials or organs which constitute

CHAPTER 11

STATE RESPONSIBILITY

offences from the point of view of the law of nations, whether the

official or organ in question has acted within or exceeded the limits of 

his competence. “It is generally agreed,” as M. Bourquin has rightly 

said, “that acts committed by the officials and agent of a State entail 

the international responsibility of that State, even if the perpetrator did 

not have specific authorization. This responsibility does not find its 

justification in general principles — I mean those principles regulating 

the judicial organization of the State. The act of an official is only 

judicially established as an act of State if such an act lies within the 

official’s sphere of competence. The act of an official operating 

beyond this competence is not an act of State. It should not in 

principle, therefore, affect the responsibility of the State. If its is 

accepted in international law that the position is different, it is for 

reasons peculiar to the mechanism of international life; it is because it

is felt that international relations would become too difficult, too 

complicated and too insecure if foreign States were obliged to take into 

account the often complex judicial arrangements that regulate 

competence in the international affairs of a State. From this it is 

immediately clear that in the hypothesis under consideration the 

international responsibility of the State is purely objective in character,

and that it rests on an idea of guarantee, in which the subjective notion 

of fault plays no part.”

But in order to be able to admit this so-called objective 

responsibility of the State for acts committed by its officials or organs 

outside their competence, they must have acted at least to all 

appearances as competent officials or organs, or they must have used 

powers or methods appropriate to their official capacity. ...

If the principles stated above are applied to the present case, and 

if it is taken into account that the perpetrators of the murder of MJ.B. 

Caire were military personnel occupying the ranks of “mayor” and 

“capitan primero” aided by a few privates, it is found that the 

conditions of responsibility formulated above are completely fulfilled. 

The officers in question, whatever their previous record, consistently 

conducted themselves as officers in the brigade of the Villista general, 

Tomas Urbina; in this capacity they began by exacting the remittance 

of certain sums of money; they continued by having the victim taken to 

a barracks of the occupying troops; and it was clearly because of the 

refusal of M. Caire to meet their repeated demands that they finally 

shot him. Under these circumstances, there remains no doubt that, even 

if they are to be regarded as having acted outside their competence, 

which is by no means certain, and even if their superior officers issued 

232 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

counter-order, these two officers have involved the responsibility of 

the State, in view of the fact that they acted in their capacity of officers 

and used the means placed at their disposition by virtue of that 

capacity.

On these grounds, I have no hesitation in stating that, in 

accordance with the most authoritative doctrine supported by 

numerous arbitral awards, the events of 11 December 1914, which led 

to the death of M J.-B. Caire, fall within the category of acts for which 

international responsibility devolves upon the State to which the 

perpetrators of the injury are amenable.

CORFU CHANNEL CASE UK 

v. Albania, [1949] ICJ Rep.

The Corfu Channel Case (United Kingdom of Great Britain and 

Northern Ireland-Albania) arose from incidents that occurred on 

October 22nd 1946, in the Corfu Strait: two British destroyers struck 

mines in Albanian waters and suffered damage, including serious loss 

of life. The two Parties concluded a Special Agreement asking the 

Court to give judgment on the following questions:

1. Is Albania responsible for the explosions, and is 

there a duty to pay compensation?

2. Has the United Kingdom violated international law 

by the acts of its Navy in Albanian waters, first on the day on 

which the explosions occurred and, secondly, on November 

12th and 13th, 1946, when it undertook a sweep of the Strait?

* * * * * 

The facts are as follows. On October 22nd, 1946, two British 

cruisers and two destroyers, coming from the south, entered the North 

Corfu Strait. The channel they were following, which was in Albanian 

waters, was regarded as safe: it had been swept in 1944 and checkswept in 1945. One of the destroyers, the Saumarez, when off Saranda, 

struck a mine and was gravely damaged. The other destroyer, the 

Volage, was sent to her assistance and, while towing her, struck 

another mine and was also seriously damaged. Forty-five British 

officers and sailors lost their lives, and forty-two others were 

wounded.

An incident had already occurred in these waters on May 15th, 

1946: an Albanian battery had fired in the direction of two

CHAPTER 11

STATE RESPONSIBILITY

233

British cruisers. The United Kingdom Government had protested, 

stating that innocent passage through straits is a right recognized by 

international law; the Albanian Government had replied that foreign 

warships and merchant vessels had no right to pass through Albanian 

territorial waters without prior authorization; and on August 2nd, 1946, 

the United Kingdom Government had replied that if, in the future, fire 

was opened on a British warship passing through the channel, the fire 

would be returned. Finally, on September 21st, 1946, the Admiralty in 

London had cabled to the British Commander-in-Chief in the 

Mediterranean to the following x effect: “Establishment of diplomatic 

relations with Albania is again under consideration by His Majesty’s 

Government who wish to know whether the Albanian Government 

have learnt to behave themselves. Information is requested whether 

any ships under your command have passed through the North Corfu 

Strait since August and, if not, whether you intend them to do so 

shortly.”

After the explosions on October 22nd, the United Kingdom 

Government sent a Note to Tirana announcing its intention to sweep 

the Corfu Channel shortly. The reply was that this consent would not 

be given unless the operation in question took place outside Albanian 

territorial waters and that any sweep undertaken in those waters would 

be a violation of Albania’s sovereignty.

The sweep effected by the British Navy took place on 

November 12th/13th 1946, in Albanian territorial waters and within 

the limits of the channel previously swept. Twenty-two moored mines 

were cut; they were mines of the German GY type.

The first question put by the Special Agreement is that of 

Albania’s responsibility, under international law, for the explosions on 

October 22nd, 1946.

The Court finds, in the first place, that the explosions were 

caused by mines belonging to the minefield discovered on November 

13th. It is not, indeed, contested that this minefield had been recently 

laid; it was in the channel, which had been previously swept and 

check-swept and could be regarded as safe, that the explosions had 

taken place. The nature of the damage shows that it was due to mines 

of the same type as those swept on November 13th; finally, the theory 

that the mines discovered on November 13th might have been laid 

after the explosions on October 22nd is too improbable to be accepted.

In these circumstances the question arises what is the legal basis 

of Albania’s responsibility? The Court does not feel that it

234 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

need pay serious attention to the suggestion that Albania herself laid 

the mines: that suggestion was only put forward pro memoria, without 

evidence in support, and could not be reconciled with the undisputed 

fact that, on the whole Albanian littoral, there are only a few launches 

and motor boats. But the United Kingdom also alleged the connivance 

of Albania: that the mine laying had been carried out by two Yugoslav 

warships by the request of Albania, or with her acquiescence. The 

Court finds that this collusion has not been proved. A charge of such 

exceptional gravity against a State would require a degree of certainty 

that has not been reached here, and the origin of the mines laid in 

Albanian territorial waters remains a matter for conjecture.

The United Kingdom also argued that, whoever might be the 

authors of the mine laying, it could not have been effected without 

Albania’s knowledge. True, the mere fact that mines were laid in 

Albanian waters neither involves prima facie responsibility nor does it 

shift the burden of proof. On the other hand, the exclusive control 

exercised by a State within its frontiers may make it impossible to 

furnish direct proof of facts which would involve its responsibility in 

case of a violation of international law. The State which is the victim 

must, in that ease, be allowed a more liberal recourse to inferences of 

fact and circumstantial evidence; such indirect evidence must be 

regarded as of especial weight when based on a series of facts, linked 

together and leading logically to a single conclusion.

In the present case two series of facts, which corroborate one 

another, have to be considered.

The first relates to the Albanian Government’s attitude before 

and after the catastrophe. The laying of the mines took place in a 

period in which it had shown its intention to keep a jealous watch on 

its territorial waters and in which it was requiring prior authorization 

before they were entered, this vigilance sometimes going so far as to 

involve the use of force: all of which render the assertion of ignorance 

a priori improbable. Moreover, when the Albanian Government had 

become fully aware of the existence of a minefield, it protested 

strongly against the activity of the British Fleet, but not against the 

laying of the mines, though this act, if effected without her consent, 

would have been a very serious violation of her sovereignty; she did 

not notify shipping of the existence of the minefield, as would be 

required by international law; and she did not undertake any of the 

measures of judicial investigation which would seem to be incumbent 

on her in such

CHAPTER 11

STATE RESPONSIBILITY

a case. Such an attitude could only be explained if the Albanian 

Government, while knowing of the mine laying, desired the 

circumstances in which it was effected to remain secret.

The second series of facts relates to the possibility of observing 

the mine laying from the Albanian coast. Geographically, the channel 

is easily watched: it is dominated by heights offering excellent 

observation points, and it runs close to the coast (the nearest mine was 

500 m. from the shore). The methodical and well-thought-out laying of 

the mines compelled the minelayers to remain from two to two-and-ahalf hours in the waters between Cape Kiephali and the St. George’s 

Monastery. In regard to that point, the naval experts appointed by the 

Court reported, after enquiry and investigation on the spot, that they 

considered it to be indisputable that, if a normal look-out was kept at 

Cape Kiephali, Denta Point, and St. George’s Monastery, and if the 

lookouts were equipped with binoculars, under normal weather 

conditions for this area, the mine-laying operations must have been 

noticed by these coastguards. The existence of a look-out post at Denta 

Point was not established; but the Court, basing itself on the 

declarations of the Albanian Government that lock-out posts were 

stationed at other points, refers to the following conclusions in the 

experts’ report: that in the case of mine laying 1) from the North 

towards the South, the minelayers would have been seen from Cape 

Kiephali; if from South towards the North, they would have been seen 

from Cape Kiephali and St. George’s Monastery.

From all the facts and observations mentioned above, the Court 

draws the conclusion that the laying of the minefield could not have 

been accomplished without the knowledge of Albania. As regards the 

obligations resulting for her from this knowledge, they are not 

disputed. It was her duty to notify shipping and especially to warn the 

ships proceeding through the Strait on October 22nd of the danger to 

which they were exposed. In fact, nothing was attempted by Albania to 

prevent the disaster, and these grave omissions involve her 

international responsibility.

NICARAGUA V. US

[1986] ICJ Rep.

VI. Establishment of the facts: evidence and methods 

employed by the Court

The Court has had to determine the facts relevant to the dispute. 

The difficulty of its task derived from the marked disagreement 

between the Parties, the non-appearance of the

236 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Respondent, the secrecy surrounding certain conduct, and the fact that 

the conflict is continuing. On this last point, the Court takes the view, 

in accordance with the general principles as to the judicial process, that 

the facts to be taken into account should be those occurring up to the 

close of the oral proceedings on the merits of the case (end of 

September 1985).

With regard to the production of evidence, the Court indicates 

how the requirements of its Statute in particular Article 53 and the 

Rules of Court have to be met in the case, on the basis that the Court 

has freedom in estimating the value of the various elements of 

evidence. It has not seen fit to order an enquiry under Article 50 of the 

Statute. With regard to certain documentary material (press articles 

and various books), the Court has treated these with caution. It regards 

than not as evidence capable of proving facts, but as material which 

can nevertheless contribute to corroborating the existence of a fact and 

be taken into account to show whether certain facts are matters of 

public knowledge. With regard to statements by representatives of 

States, sometimes at the highest level, the Court takes the view that 

such statements are of particular probative value when they

acknowledge facts or conduct unfavourable to the State represented by 

the person who made them. With regard to the evidence of witnesses 

presented by Nicaragua; five witnesses gave oral evidence and another 

a written affidavit-one consequence of the absence of the Respondent 

was that the evidence of the witnesses was not tested by crossexamination. The Court has not treated as evidence any part of the 

testimony which was a mere expression of opinion as to the 

probability or otherwise of the existence of a fact not directly known 

to the witness. With regard in particular to affidavits and sworn 

statements made by members of a Government, the Court considers 

that it can certainly retain such parts of this evidence as may be 

regarded as contrary to the interests or contentions of the State to 

which the witness has allegiance; for the rest such evidence has to be 

treated with great reserve.

The Court is also aware of a publication of the United States 

State Department entitled “Revolution Beyond Our Borders, 

Sandinista Intervention in Central America” which was not submitted 

to the Court in any form or manner contemplated by the Statute and 

Rules of Court. The Court considers that, in view of the special 

circumstances of this case, it may, within limits, make use of 

information in that publication.

CHAPTER 11

STATE RESPONSIBILITY

237

VII. The facts imputable to the United States

1. The Court examines the allegations of Nicaragua that the 

mining of Nicaraguan ports or waters was carried out by United 

States military personnel or persons of the nationality of Latin 

American countries in the pay of the United States. After examining 

the facts, the Court finds it established that, on a date in late 1983 or 

early 1984, the President of the United States authorized a United 

States Government agency to lay mines in Nicaraguan ports, that in 

early 1984 mines were laid in or close to the ports of El Bluff, 

Corinto and Puerto Sandino, either in Nicaraguan internal waters or in 

its territorial sea or both, by persons in the pay and acting on the 

instructions of that agency, under the supervision and with the logistic 

support of United States agents; that neither before the laying of the 

mines, nor subsequently, did the United States Government issue any 

public and official warning to international shipping of the existence 

and location of the mines; and that personal and material injury was 

caused by the explosion of the mines, which also created risks 

causing a rise in marine insurance rates.

2. Nicaragua attributes to the direct action of United States 

personnel, or persons in its pay, operations against oil installations, a 

naval base, etc., listed in paragraph 81 of the Judgment. The Court 

finds all these incidents, except three, to be established. Although it is

not proved that any United States military personnel took a direct part 

in the operations, United States agents participated in the planning, 

direction and support. The imputability to the United States of these 

attacks appears therefore to the Court to be established.

3. Nicaragua complains of infringement of its air space by 

United States military aircraft. After indicating the evidence 

available, the Court finds that the only violations of Nicaraguan air 

space imputable to the United States on the basis of the evidence are 

high altitude reconnaissance flights and low altitude flights on 7 to 11 

November 1984 causing “sonic booms.”

With regard to joint military manoeuvres with Honduras 

carried out by the United States on Honduran territory near the 

Honduras/Nicaragua frontier, the Court considers that they may be 

treated as public knowledge and thus sufficiently established.

4. The Court then examines the genesis, development and 

activities of the contra force, and the role of the United States in 

relation to it. According to Nicaragua, the United States “con

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

ceived, created and organized a mercenary army, the contra 

force.” On the basis of the available information, the Court is not able 

to satisfy itself that the Respondent State “created” the contra force in 

Nicaragua, but holds it established that it largely financed, trained, 

equipped, armed and organized the FDN, one element of the force.

It is claimed by Nicaragua that the United States Government 

devised the strategy and directed the tactics of the contra force, and 

provided direct combat support for its military operations. In the light 

of the evidence and material available to it, the Court is not satisfied 

that all the operations launched by the contra force, at every stage of 

the conflict, reflected strategy and tactics solely devised by the United 

States. It therefore cannot uphold the contention of Nicaragua on this 

point. The Court however finds it clear that a number of operations 

were decided and planned, if not actually by the United States 

advisers, then at least in close collaboration with them, and on the 

basis of the intelligence and logistic support which the United States 

was able to offer. It is also established in the Court’s view that the 

support of the United States for the activities of the contras took 

various forms over the years, such as logistic support the supply of 

information on the location and movements of the Sandinista troops, 

the use of sophisticated methods of communication, etc. The 

evidence does not however warrant a finding that the United States 

gave direct combat support, if that is taken to mean direct 

intervention by United States combat forces.

The Court has to determine whether the relationship of the 

contras to the United States Government was such that it would be 

right to equate the contras, for legal purposes, with an organ of the 

United States Government, or as acting on behalf of that Government. 

The Court considers that the evidence available to it is insufficient to 

demonstrate the total dependence of the contras on United States aid. 

A partial dependency, the exact extent of which the Court cannot 

establish, may be inferred from the fact that the leaders were selected 

by the United States, and from other factors such as the organization, 

training and equipping of the force, planning of operations, the 

choosing of targets and the operational support provided. There is no 

clear evidence that the United States actually exercised such a degree 

of control as to justify treating the contras as acting on its behalf.

5. Having reached the above conclusion, the Court takes 

the view that the contras remain responsible for their acts, in particular the alleged violations by them of humanitarian law. For the

CHAPTER 11

STATE RESPONSIBILITY

239

United States to be legally responsible, it would have to be proved 

that that State had effective control of the operations in the course of 

which the alleged violations were committed.

Acts of Other Persons

Article 7. The conduct of a person or group of persons shall be 

considered an act of the State under international law if the person or 

group of persons was in fact exercising elements of the governmental 

authority in the absence or default of the official authorities and in 

circumstances such as to call for the exercise of those elements of 

authority.

Article 8. The conduct of an organ placed at the disposal of a 

State by another State shall be considered an act of the former State 

under international law if the organ was acting in the exercise of 

elements of the governmental authority of the State at whose disposal 

it had been placed.

UNITED STATES V. IRAN [1980] ICJ Rep.

In its Judgment in the case concerning United States 

Diplomatic and Consular Staff in Tehran, the Court decided (1) that

Iran has violated and is skill violating obligations owed by it to the 

United States; (2) that these violations engage Iran’s responsibility; 

(3) that the Government of Iran must immediately release the United 

States nationals held as hostages and place the premises of the 

Embassy in the hands of the protecting power; (4) that no member of 

the United States diplomatic or consular staff may be kept in Iran to 

be subjected to any form of judicial proceedings or to participate in 

them as a witness; (5) that Iran is under an obligation to make 

reparation for the injury caused to the United States, and (6) that the 

form and amount of such reparation, failing agreement between the 

parties, shall be settled by the Court. (The full text of the operative 

paragraph is reproduced below.)

(a) The events of 4 November 1979 (paras. 56-68)

The first phase of the events underlying the Applicant’s claims 

covers the armed attack on the United States Embassy carried out on 4 

November 1979 by Muslim Student Followers of the Imam’s Policy 

(further referred to as “the militants” in the Judgment), the 

overrunning of its premises, the seizure of its inmates as hostages,

240 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

the appropriation of its property and archives, and the conduct of the 

Iranian authorities in the face of these occurrences.

The Court points out that the conduct of the militants on that 

occasion could be directly attributed to the Iranian State only if it 

were established that they were in fact acting on its behalf. The 

information before the Court did not suffice to establish this with due 

certainty. However, the Iranian State which, as the State to which the 

mission was accredited, was under obligation to take appropriate 

steps to protect the United States Embassy did nothing to prevent the 

attack, stop it before it reached its completion or oblige the militants 

to withdraw from the premises and release the hostages. This inaction 

was in contrast with the conduct of the Iranian authorities on several 

similar occasions at the same period, when they had taken appropriate

steps. It constituted, the Court finds, a clear and serious violation of 

Iran’s obligations to the United States under Articles 22(2), 

24,25,26,27 and 29 of the 1961 Vienna Convention on Diplomatic 

Relations, of Articles 5 and 36 of the 1963 Vienna Convention on 

Consular Relations, and of Article 11(4) of the 1955 Treaty. Further

breaches of the 1963 Convention had been involved in failure to 

protect the Consulates at Tabriz and Shiraz.

The Court is therefore led to conclude that on 4 November 

1979 the Iranian authorities were fully aware of their obligations 

under the conventions in force, and also of the urgent need for action 

on their part, that they had the means at their disposal to perform their 

obligations, but that they completely failed to do so.

(b) Events since 4 November 1979 (paras. 69-79)

The second phase of the events underlying the United States’

claims comprises the whole series of facts which occurred following 

the occupation of the Embassy by the militants. Though it was the 

duty of the Iranian Government to take every appropriate step to end 

the infringement of the inviolability of the Embassy premises and 

staff, and to offer reparation for the damage, it did nothing of the 

kind. Instead, expressions of approval were immediately heard from 

numerous Iranian authorities. Ayatollah Khomeini himself 

proclaimed the Iranian State’s endorsement of both the seizure of the 

premises and the detention of the hostages. He described the Embassy 

as a “centre of espionage,” declared that the hostages would (with 

some exceptions) remain “under arrest” until the United States had 

returned the former Shah and his property to Iran, and forbade all 

negotiation with the United

CHAPTER 11

STATE RESPONSIBILITY

States on the subject. Once organs of the Iranian State had thus given 

approval to the acts complained of and decided to perpetuate them as 

a means of pressure on the United States, those acts were transformed 

into acts of the Iranian State: the militants became agents of that 

State, which itself became internationally responsible for their acts. 

During the six months which ensued, the situation underwent no 

material change: the Court’s Order of 15 December 1979 was 

publicly rejected by Iran, while the Ayatollah declared that the 

detention of the hostages would continue until the new Iranian 

parliament had taken a decision as to their fate.

The Iranian authorities’ decision to continue the subjection of 

the Embassy to occupation, and of its staff to detention as hostages, 

gave rise to repeated and multiple breaches of Iran’s treaty 

obligations, additional to those already committed at the time of the 

seizure of the Embassy. (1961 Convention: Arts. 22, 24, 25,

26, 27 and 29 1963 Convention: inter alia, Art. 33; 1955 Treaty, 

Art. 1114]).

With regard to the Charge d’affaires and the two other members of the United States mission who have been in the Iranian 

Ministry of Foreign Affairs since 4 November 1979, the Court finds 

that the Iranian authorities have withheld from them the protection 

and facilities necessary to allow them to leave the Ministry in safety. 

Accordingly, it appears to the Court that in their respect there have 

been breaches of Articles 26 and 29 of the 1961 Vienna Convention.

Taking note, furthermore, that various Iranian authorities have 

threatened to have some of the hostages submitted to trial before a 

court, or to compel them to bear witness, the Court considers that, if 

put into effect, that intention would constitute a breach of Article 31 

of the same Convention.

Acts of Revolutionaries

Article 10. Conduct of an insurrectional or other movement

1. The conduct of an insurrectional movement, which

2. The conduct of a movement, insurrectional or other, 

which succeeds in establishing a new State in part of the territory of a

considered an act of the new State under international law.

242 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

HOME MISSIONARY SOCIETY CLAIM UJS. v. Great Britain 

(1920)

American and British Claims Arbitration Tribunal

In 1898, the collection of a tax newly imposed [by Great 

Britain] on the natives of the Protectorate [of Sierra Leone] and 

known as the “hut tax” was the signal for a serious and widespread 

revolt in the Ronietta district. The revolt broke out on April 27 and 

lasted for several days....

In the course of the rebellion all [the claimant’s]... Missions 

were attacked, and either destroyed or damaged, and some of the 

missionaries were murdered....

The contention of the United States Government before this 

Tribunal is that the revolt was the result of the imposition and 

attempted collection of the “hut tax”; that it was within the knowledge 

of the British Government that this tax was the object of deep native 

resentment; that in the face of the native danger the British 

Government wholly failed to take proper steps for the maintenance of 

order and the protection of life and property; that the loss of life and 

damage to property was the result of this neglect and failure of duty, 

and therefore that it is liable to pay compensation.

Now, even assuming that the “hut tax” was the effective cause 

of the native rebellion, it was in itself a fiscal measure in accordance 

not only with general usage in colonial administration, but also with 

the usual practice in African countries....

It was a measure to which the British Government was perfectly entitled to resort in the legitimate exercise of its sovereignty, if 

it was required....

Further, though it may be true that some difficulty might have 

been foreseen, there was nothing to suggest that it would be more 

serious than is usual and inevitable in a semi-barbarous and only 

partially colonized protectorate, and certainly nothing to lead to any 

apprehension of widespread revolt.

It is well-established principle of international law that no 

government can be held responsible for the act of rebellious bodies of 

men committed in violation of its authority, where it

CHAPTER 11

STATE RESPONSIBILITY

243

is itself guilty of no breach of good faith, or of no negligence in 

suppressing insurrection. (Moore’s INTERNATIONAL LAW DIGEST, Vol. VI, p. 956; 

VII, p. 957; Moore’s ARBITRATIONS, pp. 2991-92; British answer, p. 1)

The good faith of the British Government cannot be 

questioned, and as to the conditions prevailing in the Protectorate 

there is no evidence to support the contention that it failed in its duty 

to afford to adequate protection for life and property. ...

The Tribunal decides that this claim must be dismissed.

SHORT v. IRAN 

UJS. v. Iran (1987)

Iran-U.S. Claims Tribunal

The claimant, an American national, was employed by Lockheed, an American company, in Iran. On February 8, 1979, three days 

before the Islamic Revolutionary Government took office, the

claimant was evacuated from Iran on company orders because of the 

deteriorating situation. The claimant sought compensation for salary 

and other losses resulting from his alleged expulsion contrary to 

international law.

33. Where a revolution leads to the establishment of a new 

government the State is held responsible for the acts of the 

overthrown government insofar as the latter maintained control of the 

situation. The successor government is also held responsible for the 

acts imputable to the revolutionary movement which established it, 

even if those acts occurred prior to its establishment, as a 

consequence of the continuity existing between the new organization 

of the State and the organization of the revolutionary movement. See

Draft Articles on State Responsibility, supra, Commentary on 

Articuel 15, paras. 3 and 4....

34. The Claimant relies on acts committed by revolutionaries. ... He is unable, however, to identify any agent of the 

revolutionary movement, the actions of which compelled him to leave 

Iran. The acts of supporters of a revolution [as opposed to its agents]

cannot be attributed to the government following the success of the 

revolution just as the acts of supporters of an existing government are

not attributable to the government. This was clearly recalled by the 

International Court of Justice in United States Diplomatic and 

Consular Staff in Tehran (United States v. Iran), 19801.CJ. 3,29, 

para. 58 [above, p. 358]....

244 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

35. The Claimant.... [relies] on the declarations made by the 

leader of the Revolution, Ayatollah Khomeini... While these 

statements are of anti-foreign and in particular anti-American 

sentiments, the Tribunal notes that these pronouncements were of a 

general nature and did not specify that Americans should be expelled 

en masse. On this issue also, it is worthwhile to quote the 

International Court of Justice, in the judgment [para. 59] just referred 

to [above, p. 359], ... Similarly, it cannot be said that the declarations 

referred to by the Claimant amounted to an authorization to 

revolutionaries to act in such a way that the Claimant should be 

forced to leave Iran forthwith. Nor is there any evidence that any 

action prompted by such statements was the caused of the Claimant’s 

decision to leave Iran. In these circumstances, the Tribunal is of the

view that the Claimant has failed to prove that his departure from Iran 

can be imputed to the wrongful conduct of Iran. The claim is 

therefore dismissed.

Preliminary Objections.

When brought before an international tribunal, the claim of denial of justice 

may be lost due to failure to answer some preliminary objections. One objection

already seen is the lack of nationality link.

Another is the failure to exhaust national remedies. The obvious purpose of 

this rule is to protect international courts from being swamped with cases which 

are better handled locally. However, this rule applies only to cases founded on 

diplomatic protection or on injury to aliens. Where the case is one involving a 

treaty that touches on state rights which should be resolved on the international 

plain. Similarly, where a case involves a treaty which establishes a Claims 

Commission, it immediately goes to the Commission.

Reparation.

Article 31. Reparation

1. The responsible State is under an obligation to make full 

reparation for the injury caused by the internationally wrongful act.

2. Injury consists of any damage, whether material or 

moral, arising in consequence of the internationally wrongful act of a 

State.

Article 32. Irrelevance of internal law

The responsible State may not rely on the provisions of its 

internal law as justification for failure to comply with its obligations 

under this Part.

CHORZOW FACTORY CASE 

Germany v. Poland [1928] PCIJ

[The case concerned the expropriation by Poland of a 

factory at Chorzow contrary, as the Court had held, to the 

Geneva Convention of 1922 between Germany and Poland on 

Upper Silesia. In this judgment the Court ruled upon a claim 

by Germany for an indemnity for the damage caused by the 

illegal expropriation.]

The action of Poland which the Court has judged to be contrary 

to the Geneva Convention is not an expropriation — to render which 

lawful only the payment of fair compensation would have been 

wanting; it is a seizure of property, rights and interests which could 

not be expropriated even against compensation, save under the 

exceptional conditions fixed by Article 7 of the said Convention....

If follows that the compensation due to the German 

Government is not necessarily limited to the value of the undertaking 

at the moment of dispossession, plus interest to the day of payment. 

This limitation would only be admissible if the Polish Government 

had the right to expropriate, and if its wrongful act consisted merely 

in not having paid to the two Companies the just price of what was 

expropriated; in the present case, such a limitation might result in 

placing Germany and the interests protected by the Geneva 

Convention, on behalf of which interests the German Government is 

acting, in a situation more unfavourable than that in which Germany 

and these interest would have been if Poland had respected the said 

Convention. Such a consequence would not only be unjust, but also 

and above all incompatible with the aim of Article 6 and following 

articles of the Convention

— that is to say, the prohibition, in principle, of the liquidation of the

property, rights and interests of German nationals and of companies 

controlled by German nationals in Upper Silesia — since it would be 

tantamount to rendering lawful liquidation and unlawful 

dispossession indistinguishable in so far as their financial results are 

concerned.

The essential principle contained in the actual notion of an 

illegal act — a principle which seems to be established by interna- 

246 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

tional practice and in particular by the decisions of arbitral tribunals 

— is that reparation must, as far as possible, wipe out all the 

consequences of the illegal act and re-establish the situation which 

would, in all probability, have exited if that act had not been committed. Restitution in kind, or, if this is not possible, payment of a 

sum corresponding to the value which a restitution in kind would 

bear; the award, if need be, of damages for loss sustained which 

would not be covered by restitution in kind or payment in place of it 

— such are the principles which should serve to determine the 

amount of compensation due for an act contrary to international law.

This conclusion particularly applies as regards the Geneva 

Convention, the object of which it to provide for the maintenance of 

economic life in Upper Silesia on the basis of respect for the status 

quo. The dispossession of an industrial undertaking — the 

expropriation of which is prohibited by the Geneva Convention

— then involves the obligation to restore the undertaking and, if this 

be not possible, to pay its value at the time of the indemnification, 

which value is designed to take the place of restitution which has 

become impossible. To this obligation, in virtue of the general 

principles of international law, must be added that of compensating 

loss sustained as the result of the seizure. The impossibility, on which 

the Parties are agreed, of restoring the Chorzow factory could 

therefore have no other effect but that of substituting payment of the 

value of the undertaking for restitution; it would not be in conformity 

either with the principles of law or with the wish of the Parties to 

infer from that agreement that the question of compensation must 

henceforth be dealt with as though an expropriation properly socalled was involved.

Calvo Clause Rejected.

In the past, there were attempts to limit the ability of a state to give 

diplomatic protection to its nationals. An example of this is the “Calvo clause, ” a 

provision in a contract to the effect that “under no condition shall the intervention 

of foreign diplomatic agents in any matter related to the contract” be resorted to. 

This was rejected in North American Dredging Company Claim (1926) by the 

Mexico-United States General Claims Commission. The right to seek redress is a 

sovereign prerogative of a state and a private individual has no right to waive the 

state’s right.

CHAPTER 11

STATE RESPONSIBILITY

247

Expropriation of Alien Property.

Expropriation is the taking of property by the state. The property can be 

tangible or intangible as in the case of valuable contractual rights. Expropriation 

can be an international wrong if it is done contrary to the principles of 

international law. What are these principles?

The principles may be drawn from a 1962 UN General Assembly 

Resolution on the Sovereignty over Natural Resources which states, among others, 

that the expropriation “shall be based on grounds or reasons of public utility, 

security or the national inters which are recognized as overriding purely individual 

or private interests, both domestic and foreign. In such cases the owner shall be 

paid appropriate compensation in accordance with the rules in force in the state 

taking such measures in the exercise of its sovereignty and in accordance with 

international law.”

The rule thus recognizes the power of eminent domain as an inherent power

of sovereignty. The rule conforms with the constitutional principles of public use 

and just compensation. But international case law on the subject, generally 

between developed and developing countries, is not without disputations.

Chapter 12

INTERNATIONAL HUMAN RIGHTS LAW

From Alien Rights to Human Rights.

Early concern about human rights was about specific classes of peoples, 

e.g., slaves, minorities, and certain nationalities. It was not until the birth of the 

United Nations that human rights of all people became the subject of legislation. 

Thus, the developing doctrine on the subject is antedated by the doctrines on 

humanitarian intervention, state responsibility for injury to aliens, protection of 

minorities, League of Nation’s Mandates and Minorities Systems, and 

international humanitarian law (which is the human rights law in time of war).

Human rights, in general terms, are those inalienable and fundamental 

rights which are essential for life as human beings. But there is no agreement as to 

what these rights are. In fact, there are those who are of the view that the very 

widespread offences against human integrity and dignity are evidence that argue 

against the existence of human rights principles in international law. This is a 

profoundly negative view that must be rejected as a justification for barbarity.

There is a connection between human rights on the one hand and ethics and 

morality on the other. A distinction can perhaps be made between what are 

considered human rights precepts and the differing justification for the existence 

of such precepts. As Jacques Maritain wrote in 1949, “I am quite certain that my 

way of justifying belief in the rights of man and the ideal of liberty, equality, 

fraternity is the only way with a firm foundation in truth. This does not prevent me 

from being in agreement on these practical convictions with people who are 

certain that their way of justifying them, entirely different from mine or opposed 

to mine,... is equally the only way founded upon truth.”

Asian thinkers claim that much of what are called human rights are Western 

concepts alien to Asian culture. Nevertheless the common

248

CHAPTER 12

INTERNATIONAL HUMAN RIGHTS LAW

249

denominator between Asian and Western view so far is the belief that the 

individual must be protected and that the international community must contribute 

to the protection, even if between the two views there might be differing 

emphases: emphasis on the individual in the western (read American) outlook and 

emphasis on the community in what is called “Confucian.”

In general the Western tradition has developed from the Natural Law view 

that certain rights exist as a result of a law higher than positive or man-made law. 

And this higher law itself flows from the nature of man which demands certain 

immunities or liberties. This view flourished in the seventeenth century and 

provided a recourse against arbitrary power. Much of what the Natural Law view 

held has already become part of customary or conventional law and has served as 

a counterforce against a positivist emphasis on the importance of the state.

Literature now speaks of three generations of human rights. The first 

generation consists of the traditional civil and fundamental rights; the second 

generation, social and economic rights; third generation, right to peace, clean 

environment, self-determination, common heritage of mankind, development, 

minority rights. However, there is dispute about the cultural in human rights.

An Emerging International Bill of Human Rights.

The immediate impetus for this development was the atrocities committed 

by the regime under Adolf Hitler. What distinguishes post- World War II 

developments from earlier human rights tradition is the growing acceptance of the 

view that the way nations treat people under their jurisdiction is no longer just a 

domestic concern but also one that calls for the attention of the international 

community. This view represents a chipping away at the old concept of 

sovereignty. It recognizes that individuals can be subjects of international law and 

that they can find protection and remedies within the international community 

against abuses by their own government.

The United Nations became the cradle for the development of the new 

international law on human rights. But the U.N. Charter’s own provisions on 

human rights were preliminary. They did not make human rights law but they

represented a beginning which later would develop into international law.

250 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The Charter’s Preamble set down a fundamental premise: “faith in 

fundamental human rights, in the dignity and worth of the human person, in the 

equal rights of men and women.” Its human rights goal was set down in Article 

1(3):

To achieve international co-operation in solving international 

problems of an economic, social, cultural, or humanitarian character, 

and in promoting and encouraging respect for human rights and for 

fundamental freedoms for all without distinction as to race, sex,

language, or religion.

The achievement of these purposes was something to be worked

for.

The obligations assumed by the Organization and its Members are listed in 

two key articles:

Article 55

With a view to the creation of conditions of stability and well 

being which are necessary for peaceful and friendly relations among

nations based on respect for the principles of equal rights and selfdetermination of peoples, the United Nations shall promote:

(a) Higher standards of living, full employment, and 

conditions of economic and social progress and development;

(b) Solutions of international economic, social, health, and 

related problems; and international cultural and educational 

cooperation; and

(c) Universal respect for, and observance of, human rights 

and fundamental freedoms for all without distinction as to race, sex, 

language, or religion.

Article 56

All Members pledge themselves to take joint and separate 

action in co-operation with the Organization for the achievement of 

the purposes set forth in Article 55.

As is obvious, there are here no definitions of human rights, there is no clear 

commitment of Members to avoid violations, and there is set down no instrument 

for the correction or vindication of violations of human rights that might occur. In 

fact, the sensitivity of nations to their sovereignty is reflected in Article 2(7) of the 

U.N. Charter:

CHAPTER 12

INTERNATIONAL HUMAN RIGHTS LAW

251

Nothing contained in the present Charter shall authorize the 

United Nations to intervene in matters which are essentially within 

the domestic jurisdiction of any state or shall require the Members to 

submit such matters to settlement under the present Charter; but this 

principle shall not prejudice the application of enforcement measures 

under Chapter VII.

It is also clear, however, that the Charter itself recognized the inadequacy of 

the document; hence, through Article 62(2) it authorized the UN Social and 

Economic Council (ECOSOC) to “make recommendations for the purpose of 

promoting respect for, and the observance of, human rights and fundamental

freedoms for all” and commanded it, through Article 68, largely through the 

intervention of American non-governmental organizations, to “set up commissions 

in economic and social fields and for the promotion of human rights.”1

Vague as all these were, however, they not only marked the internationalization of human rights but they also set in motion the gradual process of 

legislating international human rights law. The first significant milestone in this 

process was the promulgation of the Universal Declaration of Human Rights.

The Universal Declaration, after many intricate delays,2 was adopted and 

proclaimed by the General Assembly on December 10, 1948. It was, however, not 

seen as law but only as “a common standard” for nations to attempt to reach. Its 

authority was primarily moral and political.3

It would take another eighteen years 

before the United Nations could convert the aspirations of the Declaration into 

conventional international law embodied in the International Covenant on Civil 

and Political Rights, the International Covenant on Economic, Social and Cultural 

Rights and the Optional Protocol to the Covenant on Civil and Political Rights.4

For a detailed history of the formulation of these Covenants, SEE Vratislav Pechota, "THE DEVELOPMENT OF THE 

COVENANT ON CIVIL AND POLITICAL RIGHTS" in L. Hbnkin, Ed., THE INTERNATIONAL BILL OF RIGHTS 32-71 (1981).

252 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

There is an important distinction between a mere declaration and a 

covenant. As Vratislav Pechota puts it:5

... [a]t the core of an international covenant lies a meeting of 

minds of the contracting parties on the specific duties and obligations 

they intend to assume, and the agreement that the undertakings must 

be effectively performed. A declaration by contrast admits the 

presumption that something less than full effectiveness in terms of 

law is intended. A covenant leaves no doubt about the legal nature of 

the provisions it contains, whereas a declaration is often deemed to 

enunciate moral rules only. Moreover, the vinculum juris created by a 

covenant generally absent from a declaration, places a duty on the 

contracting parties to bring their laws and practices into accord with 

the accepted international obligations and not to introduce new laws 

or practices which would be at variance with such obligations.

The Covenant on Civil and Political Rights.6

The substantive rights that are treated in the Covenant on Civil and Political 

Rights are found in Articles 1, and 6 to 27.

Life, liberty and property, and equality.

The Covenant’s basic provision on the right to life in Article 6(1) and its 

provision on genocide Article 6(4) and the general guarantee of liberty in Article 

9( 1) do not go beyond what Article III, Section 1 of the Philippine Bill of Rights 

guarantees. The Covenant, moreover, does not say when protected life begins, 

whereas the Philippines protects “the life of the unborn from conception.”7

Significantly, too, there is no provision on the right to property in the 

Covenant, this in spite of the fact that a provision exists in Article 17(1) in the 

Universal Declaration. Pechota explains the absence from the Covenant thus:

“While no one in the Commission questioned the right itself, there were 

considerable differences of opinion as to the restrictions to which it should be 

subject. At a time when property rights had lost much of their previous sanctity, it 

was inevitable that the

CHAPTER 12

INTERNATIONAL HUMAN RIGHTS LAW

253

Commission would find it difficult to draft a text that would command general 

acceptance.”

On the right to life, the Covenant’s Article 6(2) expresses a bias for the 

abolition of the death penalty and allows its imposition, in countries which still 

have a death penalty, only after conviction for the most serious crimes. But the 

Covenant does not stop there. In Article 6(6) it says: “Nothing in this article shall 

be invoked to delay or to prevent the abolition of capital punishment by any State 

Party to the present Covenant.” In fact, in the Second Optional Protocol to the 

Covenant, which was signed at the General Assembly meeting on December 15, 

1989, but which has not yet come into force, Article 1 says: “(1) No one within the 

jurisdiction of a State Party to the present Protocol shall be executed. (2) Each 

State Party shall take all necessary measures to abolish the death penalty within its 

jurisdiction.”

The Philippines is not yet party to the Second Protocol although it signed on

September 20,2006. The 1987 Constitution prohibited the imposition of the death 

penalty unless a new law is passed imposing death for “heinous crimes.”8

Congress first restored the death penalty for heinous crimes but Republic Act No. 

9346 has since disallowed it.

On the more detailed aspects of physical liberty, and arrests and detention 

found in Articles 8,9 and 11 of the Covenant, these are more than adequately 

covered by corresponding provisions of the Bill of Rights.9

Similarly, the rights of an accused detailed in Articles 14 and 15 of the 

Covenant have long been parts of the Philippine accusatory system as found in the 

Constitution.10 But the Covenant, in Article 14, is more restrictive in the matter of 

publicity of criminal proceedings “where the interest of juvenile persons otherwise 

requires or the proceedings concern matrimonial disputes or the guardianship of 

children.” Such standards would not easily pass the Philippine tests for publicity 

and free press."

’Article III, Sections 2,12,15 and 

‘“Article III, Sections 14 to 17.

"Article III, Section 4.

254 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

There are, however, two provisions on compensation in the Covenant which 

should be looked into. Article 9(5) says: “Anyone who has been a victim of 

unlawful arrest or detention shall have an enforceable right to compensation,” and 

Article 14(6) says that a person who has been a victim of miscarriage of justice 

“shall be compensated according to law, unless it is proved that the non-disclosure 

of the unknown fact in time is wholly or partly attributable to him.” The only 

place where the Philippine Constitution asks for compensation is in Section 12(4) 

of the Bill of Rights where the legislature is asked to compensate violations of 

rights of a person under investigation.

The guarantee of equality is found in Article 26 of the Covenant. It is the 

Bill of Rights’ more terse “equal protection” clause in Article III, Section 1. The 

guarantee is of legal equality. It does not embody the aspiration towards lesser 

material inequality. The latter is material found in the Covenant on Economic, 

Social and Cultural Rights.

Torture, ill-treatment and prison conditions

The Covenant’s proscription of torture and other forms of ill- treatment that 

offend not only against bodily integrity but also against personal dignity and the 

requirement of humane prison conditions are found in Articles 7 and 10.

While adequate prison conditions are guaranteed by Section 19(2) of the 

Bill of Rights, the fact, however, is that prison conditions in the Philippines today 

are far from adequate. It should be noted that the UN Human Rights Commission 

has expressed the view that imprisonment “in conditions seriously detrimental to a 

prisoner’s health” constitutes violation of Articles 7 and 10(1) of the Covenant.12

Freedom of Movement

The Covenant in its Article 12(1) and (2) group together the rights to travel 

within the country, the right to leave the country and the right to change one’s 

residence. The limitations on these three rights are enumerated in Article 12(3): 

“those which are provided by law, are necessary to protect national security, 

public order (ordre public), public

RIGHTS 171 (1983).

255

health or morals or the rights and freedoms of others, and are consistent with the 

other rights in the present Covenant.” They are similar to the limitations found in 

the Philippine Bill of Rights except for the fact that, unlike the Philippine 

provision, it does not require a court order for impairment of liberty of abode.

Unlike the Philippine provision, which speaks only of the right to travel 

without distinction as to whether it is travel within the country or travel from or to 

the country, the Covenant in Article 12(4) separates the right to return to one’s 

country from the right to leave one’s country. The limit to the right to return to 

one’s country in the Covenant is implied in the word “arbitrarily:” “No one shall 

be arbitrarily deprived of the right to enter his own country.” The intention of the 

Covenant in separating this right would seem to be to make the limitation more 

narrow than for the right to leave the country especially since exile is now 

prohibited by customary law and the prohibition of exile may even be jus cogens. 

It is also noteworthy that the Inter-American Commission of Human Rights has 

expressed the opinion that domestic laws which prevent exiled individuals from 

returning to their country run counter to Article 12 of the Covenant.'3

The Philippine Supreme Court, however, in the case on the return of 

Ferdinand Marcos after his involuntary exile, arrived at a different conclusion. The 

Court argued that since the Declaration of Human Rights and the Covenant on 

Human Rights separate the right to leave the country from the right to return to 

one’s country, the two rights are distinct and the right to return to one’s country is 

not guaranteed by the specific guarantees for the right to travel and liberty of 

abode and that therefore President Marcos could not appeal to Section 6 of the Bill 

of Rights. The vote, however, was a reluctant and embarrassed 8 to 7, and the 

decision was prefaced thus: “This case is unique. It should not create a precedent, 

for the case of a dictator forced out of office and into exile after causing twenty 

years of political, economic and social havoc in the country and who within the 

short space of three years seeks to return, is in a class by itself.”14

return to one’s country, a totally distinct right under international law, independent from although related to the 

right to travel” was “not among the rights specifically guaranteed in the Bill of Rights.” Human rights 

advocates would normally appeal to the Universal Declaration

256 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Related to freedom of movement is the right of aliens not to be expelled 

without due process from a territory. This is guaranteed in Article 13 of the 

Covenant.

Legal personality, privacy and the family

The right to be recognized as a person before the law is guaranteed in 

Article 16 of the Covenant. One must distinguish, however, between “having a 

legal personality” and “having a capacity to act.” The first belongs to all, whether 

citizens or aliens; the second may not be available to some by reason, for instance 

of infancy, minority, or insanity. The guarantee in its fullness means that state 

parties must “treat every human being everywhere, male or female, young or old, 

alien or citizen, as a person before the law, enjoying the protection of the law and 

of the forces of the law, with power to have rights and assume obligations: to own, 

acquire, and dispose of property; to make contracts; to sue and be sued; and to 

invoke other legal remedies.”15 There is no similar specific guarantee in the 

Constitution; but that it is presumed to exist runs through the entire document.

But when does one become a person? The Covenant does not say. The 

Philippine Constitution protects “the life of the unborn from conception;”16 but it 

does not say that the unborn is a person. The Civil Code, however, says that for 

purposes beneficial to him the unborn is considered a person.

Article 17 of the Covenant protects “privacy, family, home or 

correspondence” as well as honour and reputation.”

Articles 23 and 24 of the Covenant contain detailed provisions on the rights 

of the family and of children. These either are covered by Article XV on the 

Family in the Constitution or are so fundamental that Philippine law takes them 

for granted.

of Human Rights and to the International Covenant on Civil and Political Rights in order to seek additional 

support for the protection given by a specific country’s constitution. Justice Cortes does the opposite. She uses 

the Declaration and the Covenant to weaken the Philippine Bill of Rights.

CHAPTER 12

INTERNATIONAL HUMAN RIGHTS LAW

257

Thought, conscience, religion, expression and political freedoms

Article 18 of the Covenant guarantees “freedom of thought, conscience, and 

religion.” The limits on external exercise found in the Covenant — “to protect 

public safety, order, health, or morals or the fundamental rights of others” — if 

interpreted broadly can dilute the freedom and thus come into conflict with the 

very narrow limits allowed by the preferred position which free exercise occupies 

in the Bill of Rights. The Covenant contains explicit protection of the right of 

parents in the matter of religion for their children.

Notably, however, an established religion is not incompatible with the

Covenant.

Article 19 of the Covenant guarantees freedom of expression and Article 21 

protects the right of assembly and petition. They do not go beyond our 

Constitution’s own guarantees on the same subject. However, the Covenant’s 

Article 20 which prohibits “propaganda for war” can come into conflict with our 

Constitution’s freedom of expression.

The guarantee of political freedom in the Covenant’s Article 25 is also 

written all over the Philippine Constitution.

Associations and unions

Article 22 of the Covenant has a detailed set of provisions protecting the 

right to form associations and unions. The Covenant is silent about the right of 

government employees to form unions; the Constitution is explicit in the assertion 

of the right.

Minorities

Article 27 guarantees “ethnic, religious or linguistic minorities” the right “to 

enjoy their own culture, to profess and practice their own religion, or to use their 

own language.” This is one of the few rights which was already the subject of 

earlier treaties such as the Treaty of Versailles of 1919 and the Polish-German 

Upper Silesia Treaty of 1922.17 It is a right which is very central to the current 

conflicts in Eastern Europe.

'’Sieohart, supra, note 14, at 377.

258 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The concern for minorities has a two-fold aspect. The first is the fear of “a 

secessionist movement by minorities, threatening territorial integrity of the state, 

or about the danger of interference by other states with which the minorities are 

connected by ties of race, national origin, language, or religion.” The second is a 

genuine “concern for the human rights of minorities” and the desire “that 

minorities will flourish so as to preserve that diversity of the human race, which, 

since the beginning of mankind, has provided a motive power for the development 

of civilization and culture by weaving many strands into a single multi-colored 

tapestry.”18

Self-determination of peoples

Related to but broader than the right of minorities is the right of selfdetermination of peoples. This is treated in Article 1 of the Covenant. It has an 

interesting history and is of continuing relevance to dramatic developments that 

have happened within the past decade.

The proposal made by the USSR on the subject was to recognize the right of 

self-determination of peoples under colonial domination. But others pushed for the 

inclusion of self-determination “for peoples oppressed by despotic governments, 

peoples under alien domination, and peoples of multi-national states deprived of 

self-determination by the central authorities.”19 Article 1 now covers all of the 

above.

Self-determination covers two important rights: the right “freely to 

determine their political status and freely pursue their economic, social and 

cultural development” and the right “for their own ends, [to] freely dispose of the 

natural wealth and resources without prejudice to any obligations arising out of 

international cooperation, based upon the principle of mutual benefit, and

international law.”

Since the adoption of the Covenant, there have been at least two significant

developments. On December 14, 1960, the General Assembly adopted the 

Declaration on the Granting of Independence to Colonial Countries and Peoples, 

and on December 14,1962, it adopted the Resolution on Permanent Sovereignty 

over Natural Resources. But two questions remain: Who are “peoples” within the 

meaning of the

"Louis B. Sohn, “THE RIGHTS OF MINORITIES" in L. Henkin, Ed. supra, note 4, at 270-271.

CHAPTER 12

INTERNATIONAL HUMAN RIGHTS LAW

259

Covenant? And, since self-determination is now a legal right, what does the legal 

right include?

Certainly “peoples” include those ruled by colonial powers; but under 

present circumstances this is now of limited significance. “Peoples” also mean 

those who form a component part of a multinational state.

On the other hand, minorities as such, for which the Covenant has Article 

27, does not have a right of self-determination in the sense of the right to secede. 

Even the penultimate article of the 1960 Declaration on the Granting of 

Independence says: “Any attempt aimed at the partial or total disruption of the 

national unity and territorial integrity of a country is incompatible with purposes 

and principles of the Charter of the United Nations.”20

Self-determination has an internal and an external aspect. The internal right 

of self determination consists of the elements enumerated in the first two 

paragraphs of Article 1: the right “freely to determine their political status and 

freely pursue their economic, social and cultural development” and the right, “for 

their own ends, [to] freely dispose of the natural wealth and resources without 

prejudice to any obligations arising out of international cooperation, based upon 

the principle of mutual benefit, and international law.” These also necessarily 

include the other related political rights.

The external right of self-determination belongs to colonies and to those 

enumerated in the third paragraph: “non-self-governing and Trust Territories.”

Optional Protocol on the Covenant on Civil and Political Rights.

As a supplement to the Covenant on Civil and Political Rights, the United 

Nations adopted the Protocol to the Covenant on December 16, 1966. The 

Protocol entered into force on March 23,1976. The Philippines has ratified the 

Protocol.

This separate treaty is designed to enable private parties who are victims of 

human rights violations. But complaints may be filed only

against states which have ratified the Protocol. An eighteen-member Human 

Rights Committee created by the Covenant receives and handles the complaints.21

The Covenant on Economic, Social and Cultural Rights.22

The Covenant on Civil and Political Rights and the Covenant on Economic 

and Social and Cultural Rights were adopted on the same day. But why two 

separate documents?

The reasons for the division are both ideological and practical. 

Ideologically, the contest was between Western countries on the one hand and 

socialist and Third World countries on the other. The American delegation, for 

instance, argued that its government would find difficulty in accepting a treaty 

containing economic and cultural rights beyond those guaranteed by the

Constitution. For the socialist and Third World countries, on the other hand, the 

absence of economic, social and cultural guarantees could render civil and 

political guarantees meaningless. On the practical level, however, it became 

obvious that implementing civil and political guarantees, the classical “Thou shalt 

nots” of the Western tradition, could be done immediately; whereas the 

implementation of economic, social and cultural rights could only be done 

gradually and dependently on development conditions. In the end, the decision to 

divide, which would at least assure approval of a document on civil and political 

rights, prevailed. But significantly, Article 1 of both Covenants say exactly the 

same thing about the right of self-determination of people. Moreover, there are 

substantial overlappings on other subjects of the Covenants.

The rights specific to the Covenant on Economic, Social and Cultural 

Rights are social welfare rights stated in detail. They include: the right to work 

(Article 6), to favorable conditions of work (Article 7),

Universal Declaration of Human Rights but also to the two Covenants as well as 

to the Optional Protocol to the Covenant on Civil and Political Rights. The nation 

is therefore bound, both internally and in its foreign relations, “to bring [its] laws 

and practices into accord with the accepted international obligations and not to 

introduce new laws or practices which would be at variance with such

obligations.” As Article 2 of the Covenant on Civil and Political Rights says:

1. Each State Party to this present Covenant undertakes to respect 

and to ensure to all individuals within its territory and subject to its 

jurisdiction the rights recognized in the present Covenant, without 

distinction of any kind, such as race, colour, sex, language, religious, 

political or other opinion, national or social origin, property, birth or other 

status.

2. Where not already provided for by existing legislative or other 

measure, each State Party to the present Covenant undertakes to take the 

necessary steps, in accordance with its constitutional processes and with the 

provisions of the present Covenant, to adopt such legislative or other 

measures as may be necessary to give effect recognized in the present 

Covenant.

3. Each State Party to the present Covenant undertakes:

(a) To ensure that any person whose rights or freedoms as 

herein recognized are violated shall have an effective remedy, 

notwithstanding that the violation has been committed by any person 

acting in an official capacity;

262 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

(b) To ensure that any person claiming such a remedy shall 

have his right thereto determined by competent judicial, 

administrative or legislative authorities, or by any other competent 

authority provided for by the legal system of the State, and to 

develop the possibilities of judicial remedy;

(c) To ensure that the competent authorities shall enforce 

such remedies when granted.

As already noted, treaty commitments become part of domestic law. The 

self-executing provisions of the Covenants therefore must be implemented in 

domestic law. Those which are not self-executing must be attended to by 

“necessary steps, in accordance with its constitutional processes and with the 

provisions of the present Covenant.” This may be either by legislative or by 

executive measures.

The implementation of the provisions of the Covenant on Economic, Social 

and Cultural rights follows a pattern of its own. Article 2 says in part:

1. Each State Party to the present Covenant undertakes to take 

steps, individually and through international assistance and cooperation, 

especially economic and technical, to the maximum of its available 

resources, with a view to achieving progressively the full realization of the 

rights recognized in the present Covenant by all appropriate means, 

including particularly the adoption of legislative measures.

What governs therefore is the principle of “progressive realization” which 

means “that a state is obligated to undertake a program of activities . . . and to 

realize those rights which are ‘recognized’ by the Economic Covenant. While the 

obligation of progressive realization is limited by resource constraints, the 

Economic Covenant indicates that priority should be given to social welfare and 

that the level of effort should increase over time. These obligations apply to any 

state that has ratified the Economic Covenant, regardless of that state’s economic 

resources.”

Beyond the domestic obligations, however, and more relevantly for this 

essay, is the international obligation. In the economic and social fields, the key 

words are “cooperation” and “assistance.” “The effort to provide international 

protection for economic/social rights on the global level proceeds along many 

lines and involves actions of various kinds

CHAPTER 12

INTERNATIONAL HUMAN RIGHTS LAW

263

on behalf of these rights. The framework for this effort is the United Nations 

system, with its central organization, loosely coordinated network of specialized 

agencies, and growing body of covenants and conventions relevant to this area of 

human experience.”23 In the civil and political field, this involves participation in 

the implementation measures of the United Nations system.24

Other Conventions on Human Rights.

There have been other conventions intended for the protection of human 

rights. Among these are the 1948 Genocide Convention, the 1966 Convention on 

the Elimination of All Forms of Racial Discrimination, the 1979 Convention on 

the Elimination of All Forms of Discrimination Against Women, the 1984 

Convention Against Torture and Other Cruel, Inhuman, or Degrading Treatment or 

Punishment, the 1989 Convention on the Rights of the Child, and the 1990 

Convention on Migrants Workers.

The different regional conventions on human rights have their own 

procedure for implementation.

Customary human rights law.

It can also be said that some human rights principles have become 

customary law in the light of state practice. This would include the prohibition of 

torture, genocide, slavery and the prohibition of discrimination.

International Implementation of Human Rights Law.

Each country has the obligation to implement human rights law within its 

jurisdiction. It can be done, where proper, through municipal courts such as what 

happened in the Pena Irala case. There now exist also regional courts with 

jurisdiction over human rights violations. In addition to these, the United Nations 

itself has a system for implementation.

An important UN body is the Human Rights Commission, a subsidiary 

organ of ECOSOC. There are two different procedures used

23AGLEN MOWER, JR., International Cooperation for Social Justice 7 (1985).

24See Pedro Roman Ariston, “TAKING THE MOST SERIOUS CRIMES OF INTERNATIONAL CONCERN SERIOUSLY, ” Unpublished Juris Doctor 

Thesis presented to the Ateneo de Manila Law School, 2002.

264 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

by the Commission for responding to violations of human rights. These are (1) 

confidential consideration under ECOSOC Resolution 1503 and (2) public debate 

procedure under ECOSOC Resolution 1235. Both of these may be supplemented 

by the designation of a “thematic rapporteur” or Working Group to study 

violations of a specific character, e.g., torture, disappearance or arbitrary 

detention. There is overlapping between the two procedures.

The 1503 Procedure or confidential procedure

Resolution 1503 authorizes the Sub-Commission on Prevention of 

Discrimination and Protection of Minorities to appoint a working group consisting 

of not more than five members to meet once a year in private meetings to consider 

all communications, including replies of the governments concerned, with a view 

to bringing to the attention of the Sub-Commission those communications which 

appear to reveal a pattern of gross and reliably attested violations of human rights. 

The confidential findings of the Sub-Commission are brought to the attention of 

the Commission on Human rights. The Commission on Human Rights in turn is 

expected to submit its report and recommendation to the Economic and Social 

Council. The procedure is kept confidential until such time as the Commission on 

Human Rights decides to make recommendation to the ECOSOC.

Although the procedure is kept confidential, findings invariably find their 

way into media. Reports have touched such countries as Uruguay, Argentina, the 

Philippines and other countries.

The 1235 Procedure

This Commission on Human Rights was established in 1946 as a subsidiary 

organ of ECOSOC. For its first twenty years, it took the view that it had no 

authority to take any action with regard to reported violations of human rights. A 

significant change took place in 1967 through ECOSOC Resolution 1235, 

antedating Resolution 1503. The Resolution authorized the Commission and its

Subsidiary Commission on Prevention of Discrimination and Protection of 

Minorities to examine reports relevant to gross violations of human rights and to 

examine whether the violations revealed a consistent pattern and thereafter make 

recommendations to ECOSOC. Originally, the function referred to situation in 

South Africa, but it soon included situations in Chile, Afghanistan, Cuba, El 

Salvador, Guatemala, Iran and Iraq.

CHAPTER 12

INTERNATIONAL HUMAN RIGHTS LAW

265

As the procedure now operates, it carries out two types of activities. First, it 

holds annual public debates in which governments and NGOs are given the 

opportunity to identify publicly country specific situations which deserve 

attention. This is thus different from the confidential process under 1503. In fact, 

subjects taken up under 1503 can find their way to 1235. Second, it engages in 

studies and investigations of particular situations through the use of various 

techniques the Commission might deem appropriate.

What can result from these procedures? Various things can follow:

embarrassment of countries referred that might generate change in policy; pressure 

on governments to take the issue on a bilateral or multilateral level; statements of 

exhortation from the Commission or call from the Commission for all available 

information; the Commission might appoint a Special Rapporteur to examine and 

submit a report on the issue; the Commission might ask the Security Council to 

take up the issue with a view to promulgating sanctions.

Aside from the procedures under Resolutions 1503 and 1235, there are other 

specialized agencies which attend to specific human rights problems.

The International Criminal Court.23

A significant development in the protection of human rights is the 

International Criminal Court created by the 1998 Rome Statute. The treaty came 

into force in April 2002 when the 60th country needed to establish the 

International Criminal Court submitted its ratification. However, although nearly 

all the world’s democracy support the court, the United States continues to refuse 

ratification. Nor has the Philippine government ratified the Rome Treaty as of this 

writing.

What is the significance of the establishment of the International Criminal 

Court? Hitherto, international crimes were prosecuted in ad hoc criminal courts. 

Such were the Nuremberg and the Tokyo tribunals after World War II, and more 

recently, the tribunals for Rwanda and the former Yugoslavia. These earlier 

tribunals were undermined and weakened by the charges of politically motivated 

investigations and

a

See A. H. Robertson, “THE IMPLEMENTATION SYSTEM: INTERNATIONAL MEASURES” in L. HENKIN, supra, note 4, at 332-

369.

266 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

selective justice. Unlike the temporary tribunals, the new court will has been 

established without any specific country in mind. Thus, besides enjoying

permanency, it will begin with the virtue of neutrality so necessary for fairness. 

Gradually too, the court will be able to establish precedents.

The goal of the court, moreover, is to demand individual and not collective 

accountability. It will therefore shift the stigma of guilt away from the collectivity 

and will thereby help facilitate reconciliation by avoiding condemnation of entire 

societies. For these and other reasons some have considered its establishment “the 

single most important international institutional advance since the founding of the 

United Nations more than a half century ago.”

How will the court work? It will not function as an all purpose court. Its 

jurisdiction will be limited to the most serious international crimes: genocide, 

crimes against humanity, war crimes, and the crime of aggression. These crimes 

are carefully defined in the treaty.

An important feature of the court is the principle of complementarity. The 

court is meant to be a court of last resort. It normally must await referral of a crime 

either by a state party or by the Security Council. The court is not allowed to act 

when the local judicial system is able and willing to prosecute. Once a state has 

taken the initiative to investigate a crime, even if it ultimately decides that there is 

no reason to proceed, the international court cannot intervene. The international 

court is not intended to supplant the functioning of military and civilian tribunals 

in national judicial systems. However, if a state intentionally tries to avoid its 

international obligation by shielding a criminal from responsibility, the court may 

come in.

As can be seen, because of the principle of complementarity, the effective 

functioning of the court will depend very much on the cooperation of state parties. 

The domestic criminalization of the acts enumerated as serious crimes in the treaty 

will still have to be made by the state. In our jurisdiction, customary international 

law becomes domestic law by incorporation. Incorportion is achieved either 

through the constitutional provision which says that the general principles of 

international law are part of the law of the land or by treaty ratification. However, 

there is persuasive authority saying that treaties which criminalize certain acts are 

not self-executing.

Chapter 13

PEACEFUL SETTLEMENT OF INTERNATIONAL 

DISPUTES

The meaning of international “dispute.”

Not every disagreement is a “dispute.” A dispute in international law is a 

technical term which means “a disagreement on a point of law or fact, a conflict of 

legal views or interests between two persons.” A disagreement does not amount to 

a dispute if its resolution would have no practical effect on the relationship 

between the parties. Examples of a dispute are: disagreements over the 

interpretation of a treaty or about state boundaries or about state responsibility.

Article 2, paragraph 3 of the UN. Charter says: “All members shall settle 

their international disputes by peaceful means in such a manner that international 

peace and security, and justice, are not endangered.”

There is no general obligation to settle disputes, except perhaps those which 

according to Article 33, might endanger peace and security. But if a decision is 

made to settle disputes, the obligation is to settle them by peaceful means.

Peaceful methods of settling disputes.

The key provisions in the UN Charter are the following:

Article 33.

1. The parties to any dispute, the continuance of which is 

likely to endanger the maintenance of international peace and 

security, shall, first of all, seek a solution by negotiation, enquiry, 

mediation, conciliation, arbitration, judicial settlement, resort to 

regional agencies or arrangements, or other peaceful means of their 

own choice.

2. The Security Council shall, when it deems necessary, call 

upon the parties to settle their dispute by such means.

267

268 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Article 36

1. The Security Council may, at any stage of a dispute of 

the nature referred to in Article 33 or of a situation of like nature, 

recommend appropriate procedures or methods of adjustment.

2. The Security Council should take into consideration any 

procedures for the settlement of the dispute which have already been 

adopted by the parties.

3. In making recommendations under this Article the 

Security Council should also take into consideration that legal 

disputes should as a general rule be referred by the parties to the 

International Court of Justice in accordance with the provisions of the 

Statute of the Court.

Article 37

1. Should the parties to a dispute of the nature referred to in 

Article 33 fail to settle it by the means indicated in that Article, they 

shall refer it to the Security Council.

2. If the Security Council deems that the continuance of the 

dispute is in fact likely to endanger the maintenance of international 

peace and security, it shall decide whether to take action under Article 

36 or to recommend such terms of settlement as it may consider 

appropriate.

Article 38

Without prejudice to the provisions of Articles 33 to 37, the 

Security Council may, if all the parties to any dispute so request, 

make recommendations to the parties with a view to a pacific 

settlement of the dispute.

The peaceful means of settling disputes mentioned in the Charter may be

classified into: (a) non-judicial methods [negotiation, enquiry, mediation, 

conciliation]; (b) quasi-judicial method [arbitration]; and (c) judicial method. 

Another way of classifying them is into diplomatic and judicial methods.

Non-judicial or diplomatic methods.

Negotiation

States are generally hesitant to submit their disputes to an adjudicatory 

body. For this reason, negotiation is a preferred vehicle. There

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

269

are no set rules for negotiation. It may take place at arm’s length or face to face. 

But for a negotiated settlement to be legally binding, the parties must agree to it. 

The agreement to negotiate may be formalized in a treaty or in a simple exchange 

of notes.

A preliminary step to negotiation might be “good offices" when a neutral 

third party tries to bring two disputants together. Having been brought together, 

the usual first step, often required before judicial settlement, is negotiation. It may 

be carried out by diplomatic correspondence, face-to-face dialogue between 

permanent envoys or by designated negotiators. Essentially, negotiation is a giveand-take process of looking for a win-win solution.

Mediation

Mediation involves assistance by third parties who either act as bridge 

between parties, who do not meet, or who may sit with the disputants to chair 

meetings, suggest solutions, cajole, etc. The mediator must be approved by both 

parties.

Inquiry

Inquiry is fact-finding done by a designated group of individuals or an 

institution. When undertaken with the consent of the parties, it frequently resolves 

disputes based solely on questions of fact.

Conciliation

Conciliation is a more formal technique whereby the parties agree to refer 

controversies to an individual, a group of individuals or an institution to make 

findings of fact and recommendations. As a rule, parties do not agree to be bound 

by recommendations. But this clears the air.

Quasi-judicial method.

Arbitration

Arbitration is the binding settlement of a dispute on the basis of law by a 

non-permanent body designated by the parties. The composition, the jurisdiction 

and the rules of procedure to be applied are agreed upon by the parties in a 

compromis d’arbitrage. States cannot be required to submit to arbitration unless 

there is a previous agreement making arbitration compulsory.

270 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

What mainly distinguishes arbitration from judicial settlement is that parties 

have a greater say in deciding, for instance, the law to be applied and the 

composition of the arbitral tribunal. The process thereby becomes more flexible.

There are at least three types of arbitral agreements. The first is an 

arbitration clause that is incorporated as part of a treaty. This is commonly found 

in commercial treaties. The second type of agreement are treaties whose sole 

function is to establish methods for the arbitration of disputes. E.g., The Hague 

Convention for the Pacific Settlement of Disputes. The third type are ad-hoc 

arbitral agreements. E.g., the agreement for the settlement of claims between the 

US and Iran (1981).

Arbitral awards have made significant contribution to the development of 

international law. For instance, the arbitral award in the Las Palmas case 

established an important precedent involving acquisition of territory and decisions 

of the US-Mexican Claims Commission clarified various points on state 

responsibility.

Arbitral decisions

Arbitral tribunals apply international law unless the parties specify that 

some other law should be applied.

Under certain circumstances, arbitral decisions may be challenged. The four 

most commonly accepted bases are: that the arbitral body exceeded its powers; 

that there was corruption on the part of a member of the body; that there was 

failure to state the reasons for the awards or a serious departure from a 

fundamental rule of procedure; that the undertaking to arbitrate or the compromis

is a nullity.

Domestic courts, however, may refuse to give recognition to awards given 

by foreign arbitral tribunals under grounds found in the Convention on the 

Recognition and Enforcement of Foreign Arbitral Awards which says:

(1) a court in a state party to the Convention may deny

recognition or enforcement to a foreign arbitral award if:

(a) the agreement to arbitrate was not valid under applicable 

law;

(b) the party against which the award was rendered did not 

receive proper notice of the proceedings or was otherwise not 

afforded an opportunity to present its case;

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

271

(c) the award deals with matters outside the terms of the 

agreement to arbitrate;

(d) the constitution of the arbitral tribunal or the arbitral 

procedure was contrary to the agreement of the parties or to the law of 

the state where the arbitration took place; or

(e) the award has not yet become binding on the parties, or 

has been suspended or set aside by a competent court in the state 

where it was made.

(2) A court of a state party to the Convention may also deny 

recognition or enforcement to a foreign arbitral award that meets the 

requirements of § 487 if, under the law of that state:

(a) the subject matter of the controversy is not capable of 

settlement by arbitration; or

(b) recognition or enforcement would be contrary to public 

policy. (§488, Third Restatement.)

Judicial method: the International Court of Justice (ICJ).

The UN’s principal judicial organ is the International Court of Justice. It is 

the successor to the Permanent Court of International Justice established by the 

League of Nations. It came into being in 1945 through the Statute of the Court. All 

members of the UN are ipso facto parties to the Statute of the International Court 

of Justice. Being party to the Statute, however, does not mean acceptance of the 

jurisdiction of the Court. It simply means that the state may accept the jurisdiction 

of the court. The Statute opens the court’s door to member states. Only states may 

be parties in the court.

The cardinal rule in international courts is that states cannot be compelled to 

submit disputes to international adjudication unless they have consented to it 

either before a dispute has arisen or thereafter. States are also free to limit their 

acceptance to certain types of disputes and to attach various conditions or 

reservations to their acceptance.

Composition of the Court.

Article 2.

The Court shall be composed of a body of independent judges, elected regardless of 

their nationality from among persons

272 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

of high moral character, who possess the qualifications required in 

their respective countries for appointment to the highest judicial 

offices, or are jurisconsults of recognized competence in international 

law.

Article 3.

1. The Court shall consist of fifteen members, no two of 

whom may be nationals of the same state.

2. A person who for the purposes of membership in the Court 

could be regarded as a national of more than one state shall be 

deemed to be a national of the one in which he ordinarily exercises 

civil and political rights.

Article 26.

1. The Court may from time to time form one or more 

chambers, composed of three or more judges as the Court may 

determine, for dealing with particular categories of cases; for 

example, labour cases and cases relating to transit and 

communications.

2. The Court may at any time form a chamber for dealing 

with a particular case. The number of judges to constitute such a 

chamber shall be determined by the Court with the approval of the 

parties.

3. Cases shall be heard and determined by the chambers 

provided for in this article if the parties so request.

Article 27.

A judgment given by any of the chambers provided for in 

Articles 26 and 29 shall be considered as rendered by the Court.

Article 31.

1. Judges of the nationality of each of the parties shall retain 

their right to sit in the case before the Court.

2. If the Court includes upon the Bench a judge of the 

nationality of one of the parties, any other party may choose a person 

to sit as judge. Such person shall be chosen preferably from among 

those persons who have been nominated as candidates as provided in 

Articles 4 and 5.

3. If the Court includes upon the Bench no judge of the 

nationality of the parties, each of these parties may proceed to choose 

a judge as provided in paragraph 2 of this Article.

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

273

4. The provisions of this Article shall apply to the case of 

Articles 26 and 29. In such cases, the President shall request one or, if 

necessary, two of the members of the Court forming the chamber to 

give place to the members of the Court of the nationality of the parties 

concerned, and, failing such, or if they are unable to be present, to the 

judges specially chosen by the parties.

5. Should there be several parties in the same interest, they 

shall, for the purpose of the preceding provisions, be reckoned as one 

party only. Any doubt upon this point shall be settled by the decision 

of the Court.

6. Judges chosen as laid down in paragraphs 2, 3, and 4 of 

this Article shall fulfill the conditions required by Articles 2,

17 (paragraph 2), 20, and 24 of the present Statute. They shall take 

part in the decision on terms of complete equality with their 

colleagues.

Jurisdiction of the ICJ: Contentious jurisdiction.

The Court exercises two types of jurisdiction: contentious jurisdiction and 

advisory jurisdiction. The principal rules on contentious jurisdiction are the 

following:

Article 36.

1. The jurisdiction of the Court comprises all cases which 

the parties refer to it and all matters specially provided for in the 

Charter of the United Nations or in treaties and conventions in force.

2. The states parties to the present Statute may at any time 

declare that they recognize as compulsory ipso facto and without 

special agreement, in relation to any other state accepting the same 

obligation, the jurisdiction of the Court in all legal disputes 

concerning:

a. the interpretation of a treaty;

b. any question of international law;

c. the existence of any fact which, if established,

would constitute a breach of an international obligation;

d. the nature or extent of the reparation to be made

for the breach of an international obligation.

3. The declarations referred to above may be made 

unconditionally or on condition of reciprocity on the part of several or 

certain states, or for a certain time.

274 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

4. Such declarations shall be deposited with the SecretaryGeneral of the United Nations, who shall transmit copies thereof to the 

parties to the Statute and to the Registrar of the Court.

5. Declarations made under Article 36 of the Statute of the 

Permanent Court of International Justice and which are still in force shall 

be deemed, as between the parties to the present Statute, to be acceptances

of the compulsory jurisdiction of the International Court of Justice for the 

period which they still have to run and in accordance with their terms.

6. In the event of a dispute as to whether the Court has 

jurisdiction, the matter shall be settled by the decision of the Court.

From Article 36, the following should be noted: jurisdiction of the ICJ is 

applicable only to disputes between states and disputes are settled by international 

law and not by domestic law. But the Court has jurisdiction only when a case is 

referred to it by the parties.

There are three ways through which states may accept jurisdiction of the 

court. The first comes about on an ad hoc basis. This can happen when one party 

applies unilaterally to the Court and this application is followed by consent by the 

other state. A second way is when parties adhere to a treaty which accepts the 

jurisdiction of the court on matters of interpretation or application of the treaty. 

Finally, acceptance of jurisdiction can take place by a unilateral declaration that 

recognition of jurisdiction in relation to any other state accepting the same 

jurisdiction in all legal disputes. This last creates the optional system of submitting 

to the jurisdiction of the Court.

The optional system is operative only for states that “at any time declare that 

they recognize as compulsory ipso facto and without special agreement, in relation 

to any other state accepting the same obligation, the jurisdiction of the Court in all 

legal disputes concerning: a. the interpretation of a treaty; b. any question of 

international law; c. the existence of any fact which, if established, would 

constitute a breach of an international obligation; d. the nature or extent of the 

reparation to be made for the breach of an international obligation.” The 

Declaration is deposited with the Secretary General.

The Declaration in the optional system “may be made unconditionally or on 

condition of reciprocity on the part of several or certain states, or for a certain 

time.” States therefore can limit the extent to which they are subjecting themselves 

to the jurisdiction of

CHAPTER 13 275

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

the court. The significance of reciprocity in the matter of limitations was 

enunciated by the Court in Interhandel Case:' “Reciprocity in the case of 

Declarations accepting the compulsory jurisdiction of the Court enables a Party to 

invoke a reservation to that acceptance which it has not expressed in its own 

Declaration but which the other Party has expressed in its Declaration.” Thus, if a 

party that has made a Declaration unconditionally is brought to court by another

that has made a Declaration with conditions, the former can invoke the conditions 

in the latter’s Declaration.

The following are three cases illustrate the optional system.

AERIAL INCIDENCE CASE U.S. v. Bulgaria, ICJ 1959

The U.S. acceded to the optional clause, thereby accepting the 

compulsory jurisdiction of the ICJ, in August 1946. During the 

ratification process for that accession, however, Senator Connally

added a critical phrase to a U.S. reservation including “disputes with 

regard to matters which are essentially within the domestic 

jurisdiction of the United States of America as determined by the 

United States of America.”

On July 27, 1955, an El Al Israel airliner was driven off course 

by strong winds in very bad weather. The plane innocently crossed 

over into Bulgarian air space. While trying to return to its authorized 

course, the plane was shot down by Bulgarian military fighter planes. 

All fifty-one passengers and seven crew members aboard were killed, 

including six American nationals.

Investigators argued that the Bulgarian military failed to take 

actions required by international civil aviation agreements involving 

appropriate interception and identification of intruding aircraft.

The case was first brought to the ICJ by Israel. In that famous 

case — the Aerial Incident of July 27,1955 (Israel v. Bulgaria, 1959

I. CJ. Rep. 127) — the Court ruled that it did not have 

jurisdiction on the grounds that Bulgaria’s acceptance of the optional 

clause in the Statute of the Permanent Court of International Justice 

(the PCU, precursor to the ICJ) did not carry over to acceptance of the 

optional clause for the ICJ when Bulgaria joined the UN in

'Switzerland v. U.S., (1959) ICJ Rep.

276 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

December 1955, since Bulgaria had not been an original party to the 

UN Charter and the Statute of the ICJ.

The United States, however, pressed ahead with its claim.

On October 24, 1957, the U.S. applied to the ICJ for action 

against Bulgaria based on the violations of international law and the 

injuries to U.S. nationals. The U.S. asked Bulgaria for an award of 

$257,875 in damages, plus interest.

Bulgaria then went on to make four objections.

Objection Two: Reciprocal invocation of the Connally 

Amendment.

On the grounds of reciprocity and the consensual basis of ICJ 

jurisdiction, Bulgaria invoked the Connally Amendment reservation 

exempting from ICJ jurisdiction matters within its internal 

competence. Bulgaria contended that its airspace security and antiaircraft defenses were within its domestic jurisdiction. The Bulgarian 

government argued further that it “cannot admit that matters which it 

rightfully determines as being essentially within its domestic 

jurisdiction should be considered, directly or indirectly, before the 

Court. It requests, accordingly, that the Court declare itself without 

competence to adjudicate upon the application of the Government of 

the United States.”

The United States withdrew its application from the Court’s 

consideration. On May 30,1960, just one day before oral hearings 

were to begin, the Court formally accepted that withdrawal, ending 

the dispute.

NICARAGUA V. US

ICJ 1984

[The United States, made a Declaration in April 1984 limiting 

its Optional Clause Declaration and claimed thereby that the Court 

had no jurisdiction.]

On 14 August 1946, the United States made an Optional 

Clause Declaration with a reservation which said that:

“this declaration shall remain in force for a period of five

years and thereafter until the expiration of six months after

notice may be given to terminate this declaration.”

On 6 April 1984, when it became clear that its dispute with 

Nicaragua would be placed before the Court, the Government

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

277

of the United States deposited with the Secretary-General of the 

United Nations a notification signed by the Secretary of State, Mr. 

George Shultz (hereinafter referred to as “the 1984 notification”), 

referring to the declaration of 1946, and stating that:

“the aforesaid declaration shall not apply to disputes with any 

Central American State or arising out of or related to events in 

Central America, any of which disputes shall be settled in such 

manner as the parties to them may agree.

“Notwithstanding the terms of the aforesaid declaration, 

this proviso shall take effect immediately and shall remain in 

force for two years, so as to foster the continuing regional 

dispute settlement process which seeks a negotiated solution to 

the interrelated political, economic and security problems of 

Central America.”

In order to be able to rely upon the United States declaration of 

1946 to found jurisdiction in the present case, Nicaragua has to show 

that it was a “State accepting the same obligation” as the United 

States within the meaning of Article 36, paragraph 2, of the Statute. 

The Court found Nicaragua that it was a state accepting the same 

obligation but on the basis of a declaration it made under the Statute 

of the Permanent Court of International Justice. [Arguments towards 

this conclusion omitted.]

Finding: the Court therefore finds that the Nicaraguan 

declaration of 1929 is valid and that Nicaragua accordingly was, for 

the purposes of Article 36, paragraph 2, of the Statute of the Court, a 

“State accepting the same obligation” as the United States at the date 

of filing of the Application and could therefore rely on the United 

States declaration of 1946.

B. The declaration of the United States (paras. 52-76)

The notification of 1984 (Paras. 52-66)

The acceptance of the jurisdiction of the Court by the United 

States on which Nicaragua relies is the result of the United States 

declaration of 14 August 1946. However, the United States argues 

that effect should be given to the letter sent to the Secretary- General 

of the United Nations on 6 April 1984 (see p. 4 above). It is clear that 

if this notification were valid as against Nicaragua at the date of filing 

of the Application, the Court would not have jurisdiction under 

Article 36 of the Statute. After outlining the

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

arguments of the Parties in this connection, the Court points out that the

most important question relating to the effect of the 1984 notification is 

whether the United States was free to disregard the six months’ notice 

clause which, freely and by its own choice, it has appended to its 

declaration, in spite of the obligation it has entered into vis-a-vis other 

States which have made such a declaration. The Court notes that the United 

States has argued that the Nicaraguan declaration, being of undefined 

duration, is liable to immediate termination, and that Nicaragua has not 

accepted “the same obligation” as itself and may not rely on the time-limit 

proviso against it. The Court does not consider that this argument entitles 

the United States validly to derogate from the time-limit proviso included in 

its 1946 declaration. In the Court’s opinion, the notion of reciprocity is 

concerned with the scope and substance of the commitments entered into, 

including reservations, and not with the formal conditions of their creation, 

duration or extinction. Reciprocity cannot be invoked in order to excuse 

departure from the terms of a State’s own declaration. The United States 

cannot rely on reciprocity since the Nicaraguan declaration contains no 

express restriction at all. On the contrary, Nicaragua can invoke the six 

months’ notice against it, not on the basis of reciprocity, but because it is an 

undertaking which is an integral part of the instrument that contains it. 

The 1984 notification cannot therefore override the obligation of the United 

States to submit to the jurisdiction of the Court vis-a-vis Nicaragua.

CASE CONCERNING EAST TIMOR

Portugal v. Australia 

ICJ 1995 

(Summary)

In its Judgment the Court recalls that on 22 February 1991 Portugal 

instituted proceedings against Australia concerning “certain activities of

Australia with respect to East Timor.” According to the Application 

Australia had, by its conduct, “failed to observe — the obligation to respect 

the duties and powers of [Portugal as] the administering Power [of East 

Timor] ... and ... the right of the people of East Timor to self-determination 

and the related rights.” In consequence, according to the Application, 

Australia had “incurred international responsibility vis-a-vis both the 

people of East Timor and Portugal.”

As the basis for the jurisdiction of the Court, the Application refers 

to the declarations by which the two States have accepted

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

279

the compulsory jurisdiction of the Court under Article 36, paragraph 

2, of its Statute. In its Counter-Memorial, Australia raised questions 

concerning the jurisdiction of the Court and the admissibility of the 

Application....

The Court then gives a short description of the history of the 

involvement of Portugal and Indonesia in the Territory of East Timor 

and of a number of Security Council and General Assembly 

resolutions concerning the question of East Timor. It further describes 

the negotiations between Australia and Indonesia leading to the 

Treaty of 11 December 1989, which created a “Zone of Cooperation 

... in an area between the Indonesian Province of East Timor and 

Northern Australia.”

The Court then summarizes the contentions of both Parties.

The Court goes on to consider Australia’s objection that there is 

in reality no dispute between itself and Portugal. Australia contends

that the case as presented by Portugal is artificially limited to the 

question of the lawfulness of Australia’s conduct, and that the true

respondent is Indonesia, not Australia. Australia maintains that it is 

being sued in place of Indonesia. In this connection, it points out that 

Portugal and Australia have accepted the compulsory jurisdiction of 

the Court under Article 36, paragraph

2, of its Statute, but that Indonesia has not.

The Court finds in this respect that for the purpose of verifying 

the existence of a legal dispute in the present case, it is not relevant

whether the “real dispute” is between Portugal and Indonesia rather 

than Portugal and Australia. Portugal has, rightly or wrongly, 

formulated complaints of fact and law against Australia which the 

latter has denied. By virtue of this denial, there is a legal dispute.

The Court then considers Australia’s principal objection, to the 

effect that Portugal’s Application would require the Court to 

determine the rights and obligations of Indonesia. Australia contends 

that the jurisdiction conferred upon the Court by the Parties’ 

declarations under Article 36, paragraph 2, of the Statute would not 

enable the Court to act if, in order to do so, the Court were required to 

rule on the lawfulness of Indonesia’s entry into and continuing 

presence in East Timor, on the validity of the 1989 Treaty between 

Australia and Indonesia, or on the rights and obligations of Indonesia 

under that Treaty, even if the Court did not have to determine its 

validity. In support of its argument, it refers to the Court’s Judgment 

in the case of the Monetary Gold Removed

280 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

from Rome in 1943. Portugal agrees that if its Application required 

the Court to decide any of these questions, the Court could not 

entertain it. The Parties disagree, however, as to whether the Court is 

required to decide any of these questions in order to resolve the 

dispute referred to it.

Portugal contends first that its Application is concerned 

exclusively with the objective conduct of Australia, which consists in 

having negotiated, concluded and initiated performance of the 1989 

Treaty with Indonesia, and that this question is perfectly separable 

from any question relating to the lawfulness of the conduct of 

Indonesia.

Having carefully considered the argument advanced by 

Portugal which seeks to separate Australia’s behaviour from that of 

the Indonesia, the Court concludes that Australia’s behavior cannot be 

assessed without first entering into the question why it is that 

Indonesia could not lawfully have concluded the 1989 Treaty, while 

Portugal allegedly could have done so; the very subject-matter of the 

Court’s decision would necessarily be a determination whether, 

having regard to the circumstances in which Indonesia entered and 

remained in East Timor, it could or could not have acquired the 

power to enter into treaties on behalf of East Timor relating to the 

resources of its continental shelf. The Court could not make such a 

determination in the absence of the consent of Indonesia.

The Court rejects Portugal’s additional argument that the rights 

which Australia allegedly breached were rights erga omnes and that 

accordingly Portugal could require it, individually, to respect them 

regardless of whether or not another State had conducted itself in a

similarly unlawful manner.

In the Court’s view, Portugal’s assertion that the right of 

peoples to self-determination, as it evolved from the Charter and from 

United Nations practice, has an erga omnes character, is 

irreproachable. The principle of self-determination of peoples has 

been recognized by the United Nations Charter and in the 

jurisprudence of the Court; it is one of the essential principles of 

contemporary international law. However, the Court considers that 

the erga omnes character of a norm and the rule of consent to 

jurisdiction are two different things. Whatever the nature of the 

obligations invoked, the Court could not rule on the lawfulness of the 

conduct of a State when its judgment would imply an evaluation of 

the lawfulness of the conduct of another State which is not a party to 

the case.

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

281

The Court goes on to consider another argument of Portugal 

which, the Court observes, rests on the premise that the United 

Nations resolutions, and in particular those of the Security Council, 

can be read as imposing an obligation on States not to recognize any 

authority on the part of Indonesia over East Timor and, where the 

latter is concerned, to deal only with Portugal. Portugal maintains that 

those resolutions would constitute “givens” on the content of which 

the <tourt would not have to decide de novo.

The Court takes note of the fact that, for the two Parties, the 

Territory of East Timor remains a non-self governing territory and its 

people has the right to self-determination, and that the express 

reference to Portugal as the “administering Power” in a number of the 

above-mentioned resolutions is not at issue between them.

The Court finds, however, that it cannot be inferred from the sole fact 

that a number of resolutions of the General Assembly and the 

Security Council refer to Portugal as the administering Power of East 

Timor that they intended to establish an obligation on third States to 

treat exclusively with Portugal as regards the continental shelf of East 

Timor. Without prejudice to the question whether the resolutions 

under discussion could be binding in nature, the Court considers as a 

result that they cannot be regarded as “givens” which constitute a 

sufficient basis for determining the dispute between the Parties.

It follows from this that the Court would necessarily have to 

rule upon the lawfulness of Indonesia’s conduct as a prerequisite for

deciding on Portugal’s contention that Australia violated its obligation 

to respect Portugal’s status as administering Power, East Timor’s 

status as a non-self governing territory and the right of the people of 

the Territory to self-determination and to permanent sovereignty over 

its wealth and natural resources. Indonesia’s rights and obligations 

would thus constitute the very subject matter of such a judgment 

made in the absence of that State’s consent. Such a judgment would 

run directly counter to the “well- established principle of international 

law embodied in the Court’s Statute, namely, that the Court can only

exercise jurisdiction over a State with its consent.” (Monetary Gold 

Removed from Rome in 1943,1.CJ. Reports 1954, p. 32).

The Court accordingly finds that it is not required to consider Australia’s 

other objections and that it cannot rule on Portugal’s claims on the merits, 

whatever the importance of the questions raised by those claims and of the rules of 

international law which they bring into play.

282 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The Court recalls in any event that it has taken note in the Judgment that, for 

the two Parties, the Territory of East Timor remains a non-self governing territory 

and its people has the right to self-determination.

Provisional measures.

Article 41

1. The Court shall have the power to indicate, if it considers 

that circumstances so require, any provisional measures which ought 

to be taken to preserve the respective rights of either party.

2. Pending the final decision, notice of the measures 

suggested shall forthwith be given to the parties and to the Security 

Council

NICARAGUA V. UNITED STATES ICJ 1984

(Summary)

The Court finds that the circumstances require that it should 

indicate provisional measures, as provided by Article 41 of the 

Statute, in order to preserve the rights claimed. It emphasizes that its 

decision in no way prejudges the question of its jurisdiction to deal 

with the merits of the case and leaves unaffected the right of the 

Government of the United States and of the Government of Nicaragua 

to submit arguments in respect of such jurisdiction or such merits.

For these reasons, the Court gives the decision of which the 

complete text is reproduced below:

OPERATIVE PART OF THE ORDER

THE COURT,

A. Unanimously,

Rejects the request made by the United States of America that 

the proceedings on the Application filed by the Republic of Nicaragua 

on April 9,1984, and on the request filed the same day by the 

Republic of Nicaragua for the indication of provisional measures, be 

terminated by the removal of the case from the list;

B. pending its final decision in the proceedings instituted on 

9 April 1984 by the Republic of Nicaragua against the United States 

of America, the following provisional measures:

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

283

1. Unanimously,

The United States of America should immediately cease 

and refrain from any action restricting, blocking or endangering 

access to or from Nicaraguan ports, and, in particular, the 

laying of mines;

2. By fourteen votes to one,

The right to sovereignty and to political independence 

possessed by the Republic of Nicaragua, like any other State of 

the region or of the world, should be fully respected and should 

not in any way be jeopardized by any military and paramilitary 

activities which are prohibited by the principles of international 

law, in particular the principle that States should refrain in their 

international relations from the threat or use of force against the 

territorial integrity or the political independence of any State, 

and the principle concerning the duty not to intervene in 

matters within the domestic jurisdiction of a State, principles 

embodied in the United Nations Charter and the Charter of the 

Organization of American States.

3. Unanimously,

The Governments of the United States of America and 

the Republic of Nicaragua should each of them ensure that no 

action of any kind is taken which might aggravate or extend the 

dispute submitted to the Court .

4. Unanimously,

The Governments of the United States of America and 

the Republic of Nicaragua should each of them ensure that no 

action is taken which might prejudice the rights of the other 

Party in respect of the carrying out of whatever decision the 

Court may render in the case.

C. Unanimously,

Decides further that, until the Court delivers its final judgment 

in the present case, it will keep the matters covered by this Order 

continuously under review.

D. Unanimously,

Decides that the written proceedings shall first be addressed to 

the questions of the jurisdiction of the Court to entertain the dispute 

and of the admissibility of the Application;

284 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

And reserves the fixing of the time-limits for the said written 

proceedings, and the subsequent procedure, for further decision.

CASE CONCERNING LEGALITY OF USE OF FORCE 

Yugoslavia v. United States of America, [1999] ICJ Rep.

[This case was a request by the Federal Republic of 

Yugoslavia against the NATO states (Belgium, Canada, France, 

Germany, Italy, Netherlands, Portugal, Spain, United Kingdom and 

United States) in relation to the bombings being carried out by the 

NA 8:00 AM forces]

15. Whereas, the Court is deeply concerned with the human 

tragedy, the loss of life, and the enormous suffering in Kosovo which 

form the background of the present dispute, and with the continuing 

loss of life and human suffering in all parts of Yugoslavia;

16. Whereas, the Court is profoundly concerned with the use 

of force in Yugoslavia; whereas under the present circumstances such 

use raises very serious issues of international law;

17. Whereas, the Court is mindful of the purposes and 

principles of the United Nations Charter and of its own responsibilities in the maintenance of peace and security under the Charter 

and the Statute of the Court;

18. Whereas, the Court deems it necessary to emphasize that 

all parties appearing before it must act in conformity with their 

obligations under the United Nations Charter and other rules of 

international law, including humanitarian law;

* * *

19. Whereas, the Court, under its Statute, does not 

automatically have jurisdiction over legal disputes between States 

parties to that Statute or between other States to whom access to the 

Court has been granted; whereas the Court has repeatedly stated “that 

one of the fundamental principles of its Statute is that it cannot decide 

a dispute between States without the consent of those States to its 

jurisdiction” (East Timor, Judgment, I.CJ. Reports 1995, p. 101, 

para. 26); and whereas, the Court can therefore exercise jurisdiction 

only between States parties to a dispute who not only have access to

the Court but also have accepted the jurisdiction of the Court, either 

in general form or for the individual dispute concerned;

20. Whereas, on a request for provisional measures the Court 

need not, before deciding whether or not to indicate them,

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

finally satisfy itself that it has jurisdiction on the merits of the case, 

yet it ought not to indicate such measures unless the provisions 

invoked by the applicant appear,prima facie, to afford a basis on 

which the jurisdiction of the Court might be established;

21. Whereas, in its Application Yugoslavia claims, in the 

first place, to found the jurisdiction of the Court upon Article IX of 

the Genocide Convention, which provides:

“Disputes between the Contracting Parties relating to the

interpretation, application or fulfillment of the present 

Convention, including those relating to the responsibility of a 

State for genocide or for any of the other acts enumerated in 

Article III, shall be submitted to the International Court of 

Justice at the request of any of the parties to the dispute”;

Whereas, it is not disputed that both Yugoslavia and the 

United States are parties to the Genocide Convention; but 

whereas, when the United States ratified the Convention on 25 

November 1988, it made the following reservation: “That with 

reference to Article IX of the Convention, before any dispute to 

which the United States is a party may be submitted to the 

jurisdiction of the International Court of Justice under this 

Article, the specific consent of the United States is required in 

each case”;

22. Whereas, the United States contends that “[its] reservation [to Article IX] is clear and unambiguous”; that “[t]he United 

States has not given the specific consent [that reservation] requires 

[and]... will not do so”; and that Article IX of the Convention cannot 

in consequence found the jurisdiction of the Court in this case, even 

prima facie; whereas, the United States also observed that 

reservations to the Genocide Convention are generally permitted; that 

its reservation to Article IX is not contrary to the Convention’s object 

and purpose; and that, “[s]ince ... Yugoslavia did not object to the ...

reservation, [it] is bound by it”; and whereas the United States further 

contends that there is no “legally sufficient ... connection between the 

charges against the United States contained in the Application and 

[the] supposed jurisdictional basis under the Genocide Convention”; 

and whereas the United States further asserts that Yugoslavia has 

failed to make any credible allegation of violation of the Genocide 

Convention, by failing to demonstrate the existence of the specific 

intent required by the Convention to “destroy, in whole or in part, a 

national, ethnical, racial or religious group, as such,” which intent 

could not be inferred from the conduct of conventional military 

operations against another State.

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

23. Whereas, Yugoslavia disputed the United States 

interpretation of the Genocide Convention, but submitted no 

argument concerning the United States reservation to Article IX of 

the Convention;

24. Whereas, the Genocide Convention does not prohibit 

reservations; whereas, Yugoslavia did not object to the United States 

reservation to Article IX; and whereas, the said reservation had the 

effect of excluding that Article from the provisions of the Convention 

in force between the Parties;

25. Whereas, in consequence Article IX of the Genocide 

Convention cannot found the jurisdiction of the Court to entertain a 

dispute between Yugoslavia and the United States alleged to fall 

within its provisions; and whereas, that Article manifestly does not 

constitute a basis of jurisdiction in the present case, even prima facie; 

* * 

26. Whereas, in its Application Yugoslavia claims, in the 

second place, to found the jurisdiction of the Court on Article 38, 

paragraph 5, of the Rules of Court, which reads as follows:

“5. When the applicant State proposes to found the 

jurisdiction of the Court upon a consent thereto yet to be given 

or manifested by the State against which such application is 

made, the application shall be transmitted to that State. It shall 

not however be entered in the General List, nor any action be 

taken in the proceedings, unless and until the State against 

which such application is made consents to the Court’s 

jurisdiction for the purposes of the case”;

27. Whereas, the United States observes that it “has not 

consented to jurisdiction under Article 38, paragraph 5 [of the Rules 

of Court] and will not do so”;

28. Whereas, it is quite clear that, in the absence of consent 

by the United States, given pursuant to Article 38, paragraph 5, of the 

Rules, the Court cannot exercise jurisdiction in the present case, even 

prima facie\

* * 

29. Whereas, it follows from what has been said above that 

the Court manifestly lacks jurisdiction to entertain Yugoslavia’s 

Application; whereas it cannot therefore indicate any provisional 

measure whatsoever in order to protect the rights invoked therein;

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

287

and whereas, within a system of consensual jurisdiction, to maintain 

on the General List a case upon which it appears certain that the Court

will not be able to adjudicate on the merits would most assuredly not 

contribute to the sound administration of justice;

* * 

30. Whereas, there is a fundamental distinction between the 

question of the acceptance by a State of the Court’s jurisdiction and 

the compatibility of particular acts with international law; the former 

requires consent; the latter question can only be reached when the 

Court deals with the merits after having established its jurisdiction 

and having heard full legal arguments by both parties;

31. Whereas, whether or not States accept the jurisdiction of 

the Court, they remain in any event responsible for acts attributable to 

them that violate international law, including humanitarian law; 

whereas any disputes relating to the legality of such acts are required 

to be resolved by peaceful means, the choice of which, pursuant to 

Article 33 of the Charter, is left to the parties;

32. Whereas, in this context the parties should take care not 

to aggravate or extend the dispute;

33. Whereas, when such a dispute gives rise to a threat to the 

peace, breach of the peace or act of aggression, the Security Council 

has special responsibilities under Chapter VII of the Charter;

* * 

34. For these reasons,

The Court,

(1) By twelve votes to three,

Rejects the request for the indication of provisional measures 

submitted by the Federal Republic of Yugoslavia on 29 April 1999;

Intervention.

Article 62.

1. Should a state consider that it has an interest of a legal 

nature which may be affected by the decision in the case, it may 

submit a request to the Court to be permitted to intervene.

2. It shall be for the Court to decide upon this request.

288 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Article 63.

1. Whenever the construction of a convention to which 

states other than those concerned in the case are parties is in question, 

the Registrar shall notify all such states forthwith.

2. Every state so notified has the right to intervene in the 

proceedings; but if it uses this right, the construction given by the

judgment will be equally binding upon it.

EL SALVADOR V. HONDURAS

Nicaragua Intervention [1992] ICJ Rep.

In its Application for permission to intervene, filed on 17 

November 1989, Nicaragua stated that the Application was made by 

virtue of Article 36, paragraph 1, and Article 62 of the Statute.

***** The Chamber observes that as the Court has made 

clear in previous cases, in order to obtain permission to intervene

under Article 62 of the Statute, a State has to show an interest of a 

legal nature which may be affected by the Court’s decision in the case 

...

(b) Object of the intervention

The Chamber turns to the question of the object of Nicaragua’s 

Application for permission to intervene in the case. A statement of

the “precise object of the intervention” is required by Article 81, 

paragraph 2(b), of the Rules of Court.

Nicaragua’s indication, in its Application for permission to 

intervene, of the object of its intervention in the present case, is as 

follows:

“The intervention for which permission is requested has 

the following objects:

“First, generally to protect the legal rights of the Republic of Nicaragua in the Gulf of Fonseca and the adjacent 

maritime areas by all legal means available.

“Secondly, to intervene in the proceedings in order to 

inform the Court of the nature of the legal rights of Nicaragua 

which are in issue in the dispute. This form of inter

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

289

vention would have the conservative purpose of seeking to 

ensure that the determination of the Chamber did not trench 

upon the legal rights and interests of the Republic of Nicaragua.”

* * * * * 

So far as the object of Nicaragua’s intervention is “to inform 

the Court of the nature of the legal rights of Nicaragua which are in 

issue in the dispute,” it cannot be said that this object is not a proper 

one: it seems indeed to accord with the function of intervention. ... 

Secondly, it does not seem to the Chamber that for a State to seek by 

intervention “to protect its claims by all legal means” necessarily 

involves the inclusion in such means of “that of seeking a favourable 

judicial pronouncement” on its own claims. The “legal means 

available” must be those afforded by the institution of intervention for 

the protection of a third State’s legal interests. So understood, that 

object cannot be regarded as improper.

* * * * * 

The Chamber has now further to consider the argument of El 

Salvador that for Nicaragua to intervene it must in addition show a 

“valid link of jurisdiction” between Nicaragua and the Parties. In its 

Application, Nicaragua does not assert the existence of any basis of 

jurisdiction other than the Statute itself, and expresses the view that 

Article 62 does not require a separate title of jurisdiction.

The question is whether the existence of a valid link of 

jurisdiction with the parties to the case — in the sense of a basis of 

jurisdiction which could be invoked, by a State seeking to intervene, 

in order to institute proceedings against either or both of the parties —

is an essential condition for the granting of permission to intervene 

under Article 62 of the Statute. In order to decide the point, the 

Chamber must consider the general principle of consensual 

jurisdiction in its relation with the institution of intervention.

There can be no doubt of the importance of this general 

principle. The pattern of international judicial settlement under the 

Statute is that two or more States agree that the Court shall hear and 

determine a particular dispute. Such agreement may be given ad hoc, 

by Special Agreement or otherwise, or may result from the 

invocation, in relation to the particular dispute, of a compromissory 

clause of a treaty or of the mechanism of Article 36, paragraph 2, of 

the Court’s Statute. Those States are the “parties” to the proceedings,

and are bound by the Court’s eventual decision

290 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

because they have agreed to confer jurisdiction on the Court to decide

the case, the decision of the Court having binding force as provided 

for in Article 59 of the Statute. Normally therefore, no other State 

may involve itself in the proceedings without the consent of the 

original parties. Nevertheless, procedures for a “third” State to 

intervene in a case are provided in Articles 62 and 63 of the Court’s 

Statute. The competence of the Court in this matter of intervention is 

not, like its competence to hear and determine the dispute referred to 

it, derived from the consent of the parties to the case, but from the 

consent given by them, in becoming parties to the Court’s Statute, to 

the Court’s exercise of its powers conferred by the Statute. Thus, the 

Court has the competence to permit an intervention even though it be 

opposed by one or both of the parties to the case. The nature of the 

competence thus created by Article 62 of the Statute is definable by 

reference to the object and purpose of intervention, as this appears 

from Article 62 of the Statute.

Intervention under Article 62 of the Statute is for the purpose of 

protecting a State’s “interest of a legal nature” that might be affected

by a decision in an existing case already established between other 

States, namely the parties to the case. It is not intended to enable a 

third State to tack on a new case, to become a new party, and so have 

its own claims adjudicated by the Court. Intervention cannot have 

been intended to be employed as a substitute for contentious 

proceedings. Acceptance of the Statute by a State does not of itself 

create jurisdiction to entertain a particular case: the specific consent 

of the parties is necessary for that. If an intervener were held to 

become a party to a case merely as a consequence of being permitted 

to intervene in it, this would be a very considerable departure from 

the principle of consensual jurisdiction. It is therefore clear that a 

State, which is allowed to intervene in a case, does not, by reason 

only of being an intervener, become also a party to the case.

It thus follows from the juridical nature and from the purposes 

of intervention that the existence of a valid link of jurisdiction 

between the would-be intervener and the parties is not a requirement 

for the success of the application. On the contrary, the procedure of

intervention is to ensure that a State with possibly affected interests 

may be permitted to intervene even though there is no jurisdictional 

link and it therefore cannot become a party. The Chamber therefore 

concludes that the absence of a jurisdictional link between Nicaragua 

and the Parties to this case is no bar to permission being given for 

intervention.

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

IV. Procedural Rights of State permitted to intervene

Since this is the first case in the history of the two Courts in 

which a State will have been accorded permission to intervene under 

Article 62 of the Statute, it appears appropriate to give some 

indication of the extent of the procedural rights acquired by the 

intervening State as a result of that permission. In the first place, as 

has been explained above, the intervening State does not become 

party to the proceedings, and does not acquire the rights, or become

subject to the obligations, which attach to the status of a party, under

the Statute and Rules of Court, or the general principles of procedural 

law. Nicaragua, as an intervener, has of course a right to be heard by 

the Chamber. That right is regulated by Article 85 of the Rules of 

Court, which provides for submission of a written statement, and 

participation in the hearings.

The scope of the intervention in this particular case, in relation 

to the scope of the case as a whole, necessarily involves limitations of 

the right of the intervener to be heard. An initial limitation is that it is 

not for the intervener to address argument to the Chamber on the 

interpretation of the Special Agreement concluded between the Parties 

on 24 May 1986, because the Special Agreement is, for Nicaragua, 

res inter alios acta; and Nicaragua has disclaimed any intention of 

involving itself in the dispute over the land boundary. The Chamber 

then summarizes the aspects of the case in respect of which Nicaragua 

has shown the existence of an interest of a legal nature and those in 

respect of which it has not, with the consequent limitations on the 

scope of the intervention permitted.

Obligation to comply with decisions.

Article 59 (ICJ Statute)

The decision of the Court has no binding force except between 

the parties and in respect of that particular case.

Article 60

The judgment is final and without appeal. In the event of 

dispute as to the meaning or scope of the judgment, the Court shall 

construe it upon the request of any party.

Article 61

1. An application for revision of a judgment may be made 

only when it is based upon the discovery of some fact of such a nature 

as to be a decisive factor, which fact was, when the

292 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

judgment was given, unknown to the Court and also to the party 

claiming revision, always provided that such ignorance was not due 

to negligence.

2. The proceedings for revision shall be opened by a 

judgment of the Court expressly recording the existence of the new

fact, recognizing that it has such a character as to lay the case open to 

revision, and declaring the application admissible on this ground.

3. The Court may require previous compliance with the 

terms of the judgment before it admits proceedings in revision.

4. The application for revision must be made at latest 

within six months of the discovery of the new fact.

5. No application for revision may be made after the lapse 

of ten years from the date of the judgment.

Article 94 (UN Charter)

1. Each Member of the United Nations undertakes to 

comply with the decision of the International Court of Justice in any 

case to which it is a party.

2. If any party to a case fails to perform the obligations 

incumbent upon it under a judgment rendered by the Court, the other 

party may have recourse to the Security Council, which may, if it 

deems necessary, make recommendations or decide upon measures to 

be taken to give to the judgment.

ICJ judgments are binding on the parties (Art. 59) and are deemed “final 

and without appeal.” (Art. 60).

Enforcement is governed by Article 94 of the UN Charter. Member states 

must comply with the judgment. If a party does not comply, the aggrieved party 

may appeal to the UN Security Council “which may, if it deems necessary, make 

recommendations or decide upon measures to be taken to give effect to the 

judgment.” This may give rise to enforcement measures, which, however, is 

subject to the veto powers of the permanent members. But the winning state might 

make use of alternative methods of enforcement such as diplomatic or economic 

pressure.

Advisory jurisdiction.

Under Article 65 of the Statute, the advisory jurisdiction may “in 

accordance with the Charter of the United Nations.” Article 96 of the

CHAPTER 13

PEACEFUL SETTLEMENT OF INTERNATIONAL DISPUTES

293

UN Charter empowers the General Assembly and the Security Council to make 

requests for advisory opinion. At the same time the General Assembly may 

authorize other UN agencies to seek advisory opinion. The provisions of the ICJ 

Statute say:

Article 65.

1. The Court may give an advisory opinion on any legal 

question at the request of whatever body may be authorized by or in 

accordance with the Charter of the United Nations to make such a 

request.

2. Questions upon which the advisory opinion of the Court 

is asked shall be laid before the Court by means of a written request 

containing an exact statement of the question upon which an opinion 

is required, and accompanied by all documents likely to throw light 

upon the question.

Article 66.

1. The Registrar shall forthwith give notice of the request 

for an advisory opinion to all states entitled to appear before the 

Court.

2. The Registrar shall also, by means of a special and direct 

communication, notify any state entitled to appear before the Court or 

international organization considered by the Court, or, should it not be 

sitting, by the President, as likely to be able to furnish information on 

the question, that the Court will be prepared to receive, within a time 

limit to be fixed by the President, written statements, or to hear, at a 

public sitting to be held for the purpose, oral statements relating to the 

question.

3. Should any such state entitled to appear before the Court 

have failed to receive the special communication referred to in 

paragraph 2 of this Article, such state may express a desire to submit 

a written statement or to be heard; and the Court will decide.

4. States and organizations having presented written or oral 

statements or both shall be permitted to comment on the statements 

made by other states or organizations in the form, to the extent, and 

within the time limits which the Court, or, should it not be sitting, the 

President, shall decide in each particular case. Accordingly, the 

Registrar shall in due time communicate any such written statements 

to states and organizations having submitted similar statements.

294 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

For its part the UN Charter says:

Article 96.

1. The General Assembly or the Security Council may request 

the International Court of Justice to give an advisory opinion on any legal 

question.

2. Other organs of the United Nations and specialized agencies, 

which may at any time be so authorized by the General Assembly, may also 

request advisory opinions of the Court on legal questions arising within the 

scope of their activities.

By definition advisory opinions are non-binding. Acceptance or nonacceptance of the advisory opinion is determined by the internal law of the 

institution.

Other more active International Courts.

The more active are the Court of Justice of the European Communities, the 

European Court of Human Rights, the Benelux Court of Justice and the InterAmerican Court of Human Rights. The International Criminal Court entered into 

force only in 2002.

Chapter 14

THE USE OF FORCE SHORT OF WAR

The Use of Force.

The general principle is that international law recognizes the autonomy of 

individual states and their right to freedom from coercion and to the integrity of 

their territory. The basic principle is found in Article 2(4) of the UN Charter: “All 

Members shall refrain in their international relations from the threat or use of force 

against the territorial integrity or political independence of any state, or in any 

other manner inconsistent with the Purposes of the United Nations.”

It is noteworthy that the text does not use the word “war.”

The word war is a technical term which does not include some uses of force. 

The prohibition in the Charter therefore broader than the prohibition of 

war. Similarly, it should be noted that the text does not merely prohibit the 

use of force “against the territorial integrity or political independence of any 

state.” The text broadly prohibits the use of force “in any other manner 

inconsistent with the Purposes of the United Nations.” It does yield the 

meaning of a very broad prohibition of the use of force because the 

purposes of the United Nations, as found in Article 1 of the Charter, go 

beyond merely the protection of the territorial integrity and political 

independence of states.

It will be recalled that the Corfu Channel case

1

dealt with British warships 

which had been struck by mines while exercising the right of innocent passage in 

Albanian territory. Britain sent additional warships to sweep the minefields within 

Albanian territory. The Court used language in support of a broad prohibition of 

force:

'(1949) ICJ Rep.

295

296 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The United Kingdom has stated that its object was to secure the mines as 

quickly as possible for fear lest they should be taken away by the authors of the 

mine laying or by the Albanian authorities: this was presented either as a new and 

special application of the theory of intervention, by means of which the 

intervening State was acting to facilitate the task of the international tribunal, or as 

a method of selfprotection or self-help. The Court cannot accept these lines of 

defence. It can only regard the alleged right of intervention as the manifestation of 

a policy of force which cannot find a place in international law. As regards the 

notion of self-help, the Court is also unable to accept it: between independent 

States the respect for territorial sovereignty is an essential foundation for 

international relations....

The prohibition of the use of force, however, is not just conventional law. It 

is customary international law. In Nicaragua v. US,2

the Court made this 

pronouncement:

The Court finds that both Parties take the view that the 

principles as to the use of force incorporated in the United Nations 

Charter correspond, in essentials, to those found in customary 

international law. They therefore accept a treaty-law obligation to 

refrain in their international relations from the threat or use of force 

against the territorial integrity or political independence of any State, 

or in any other manner inconsistent with the purposes of the United 

Nations (Art. 2, para. 4, of the Charter). The Court has however to be 

satisfied that there exists in customary law an opinio juris as to the 

binding character of such abstention. It considers that this opinio juris

may be deduced from, inter alia, the attitude of the Parties and of 

States towards certain General Assembly resolutions, and particularly 

resolution 2625 (XXV) entitled “Declaration on Principles of 

International Law concerning Friendly Relations and Co-operation 

among States in Accordance with the Charter of the United Nations.” 

Consent to such resolutions is one of the forms of expression of an 

opinio juris with regard to the principle of nonuse of force, regarded 

as a principle of customary international law, independently of the 

provisions, especially those of an institutional kind, to which it is 

subject on the treaty-law plane of the Charter.

2

( 1986) ICJ Rep.

CHAPTER 14

THE USE OF FORCE SHORT OF WAR

297

A separate opinion was filed by Judge Sette-Camara:

Judge Sette-Camara fully concurs with the Judgment because 

he firmly believes that “the non-use of force as well as nonintervention — the latter as a corollary of equality of States and selfdetermination — are not only cardinal principles of customary 

international law but could in addition be recognized as peremptory 

rules of customary international law which impose obligations on all 

States.”

The Threat of Force.

The Charter prohibits not just the use of force but also the threat of force. 

The most typical form of this threat is the ultimatum in which the State to which it 

is addressed is given a time-limit within which to accept the demands made upon it 

and is told that, if it rejects the demands, war will be declared on it or certain 

coercive measures such as a naval blockade, bombardment, or occupation of a 

given territory, will be taken. However, the threat to use force is not always made 

in so crude and open a form. There are sometimes veiled threats that may be very 

effective, but are difficult to detect.

Threat of force was discussed by the ICJ in an advisory opinion on the 

Legality of the Threat or Use of Nuclear Weapons3

in the light of the provisions of 

the Charter:

In Article 2, paragraph 4, of the Charter the use of force against 

the territorial integrity or political independence of another State or in 

any other manner inconsistent with the purposes of the United 

Nations is prohibited.

This prohibition of the use of force is to be considered in the 

light of other relevant provisions of the Charter. In Article 51, the 

Charter recognizes the inherent right of individual or collective selfdefence if an armed attack occurs. A further lawful use of force is 

envisaged in Article 42, whereby the Security Council may take 

military enforcement measures in conformity with Chapter VII of the 

Charter.

These provisions do not refer to specific weapons. They apply 

to any use of force, regardless of the weapons employed.

3

(1996) ICJ Rep.

298 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

The Charter neither expressly prohibits, nor permits, the use of any 

specific weapon, including nuclear weapons.

The entitlement to resort to self-defence under Article 51 is 

subject to the conditions of necessity and proportionality. As the 

Court stated in the case concerning Military and Paramilitary Activities in and against Nicaragua (Nicaragua v. United States of 

America) (I.CJ. Reports 1986,p. 94,para. 176): “there is a specific 

rule whereby self-defence would warrant only measures which are 

proportional to the armed attack and necessary to respond to it, a rule 

well-established in customary international law.”

The proportionality principle may thus not in itself exclude the 

use of nuclear weapons in self-defence in all circumstances.

But at the same time, a use of force that is proportionate under the 

law of self-defence, must, in order to be lawful, also meet the requirements of the law applicable in armed conflict which comprise in 

particular the principles and rules of humanitarian law. And the Court 

notes that the very nature of all nuclear weapons and the profound 

risks associated therewith are further considerations to be borne in 

mind by States believing they can exercise a nuclear response in selfdefence in accordance with the requirements of proportionality.

In order to lessen or eliminate the risk of unlawful attack,

States sometimes signal that they possess certain weapons to use in 

self-defence against any State violating their territorial integrity or 

political independence. Whether a signaled intention to use force if 

certain events occur is or is not a “threat” within Article 2, paragraph 

4, of the Charter depends upon various factors. The notions of 

“threat” and “use” of force under Article 2, paragraph 4, of the 

Charter stand together in the sense that if the use of force itself in a 

given case is illegal — for whatever reason — the threat to use such 

force will likewise be illegal. In short, if it is to be lawful, the 

declared readiness of a State to use force must be a use of force that is 

in conformity with the Charter. For the rest, no State — whether or 

not it defended the policy of deterrence — suggested to the Court that 

it would be lawful to threaten to use force if the use of force 

contemplated would be illegal.

Individual and Collective Self-defense.

The general prohibition of the use of force does not preclude the

right to self-defense. This is the subject of Article 51:

CHAPTER 14

THE USE OF FORCE SHORT OF WAR

299

Nothing in the present Charter shall impair the inherent right of 

individual or collective self-defence if an armed attack occurs against 

a Member of the United Nations, until the Security Council has taken 

measures necessary to maintain international peace and security. 

Measures taken by Members in the exercise of this right of selfdefence shall be immediately reported to the Security Council and 

shall not in any way affect the authority and responsibility of the 

Security Council under the present Charter to take at any time such 

action as it deems necessary in order to maintain or restore 

international peace and security.

The subject was discussed at some length in Nicaragua v. USA*

The Court finds that both Parties take the view that the 

principles as to the use of force incorporated in the United Nations 

Charter correspond, in essentials, to those found in customary 

international law. They therefore accept a treaty-law obligation to 

refrain in their international relations from the threat or use of force 

against the territorial integrity or political independence of any State, 

or in any other manner inconsistent with the purposes of the United 

Nations (Art. 2, para. 4, of the Charter). The Court has however to be 

satisfied that there exists in customary law an opinio juris as to the 

binding character of such abstention. It considers that this opinio juris

may be deduced from, inter alia, the attitude of the Parties and of 

States towards certain General Assembly resolutions, and particularly 

resolution 2625 (XXV) entitled “Declaration on Principles of

International Law concerning Friendly Relations and Co-operation 

among States in Accordance with the Charter of the United Nations.” 

Consent to such resolutions is one of the forms of expression of an 

opinio juris with regard to the principle of nonuse of force, regarded 

as a principle of customary international law, independently of the 

provisions, especially those of an institutional kind, to which it is 

subject on the treaty-law plane of the Charter.

The general rule prohibiting force established in customary law 

allows for certain exceptions. The exception of the right of individual 

or collective self-defence is also, in the view of States, established in 

customary law, as is apparent for example from the terms of Article 

51 of the United Nations Charter, which refers to an “inherent right,” 

and from the declaration in resolution 2625

‘(1986) ICJ Rep.

300 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

(XXV). The Parties, who consider the existence of this right to be 

established as a matter of customary international law, agree in 

holding that whether the response to an attack is lawful depends on 

the observance of the criteria of the necessity and the proportionality 

of the measures taken in self-defence.

Whether self-defence be individual or collective, it can only be 

exercised in response to an “armed attack.” In the view of the Court, 

this is to be understood as meaning not merely action by regular 

armed forces across an international border, but also the sending by a 

State of armed bands on to the territory of another State, if such an 

operation, because of its scale and effects, would have been classified 

as an armed attack had it been carried out by regular armed forces. 

The Court quotes the definition of aggression annexed to General 

Assembly resolution 3314 (XXIX) as expressing customary law in 

this respect.

The Court does not believe that the concept of “armed attack” 

includes assistance to rebels in the form of the provision of weapons 

or logistical or other support. Furthermore, the Court finds that in

customary international law, whether of a general kind or that 

particular to the inter-American legal system, there is no rule 

permitting the exercise of collective self-defence in the absence of a 

request by the State which is a victim of the alleged attack, this being 

additional to the requirement that the State in question should have 

declared itself to have been attacked.

The question has also been raised whether “anticipatory self- defense” is 

allowed. ... The question is valid because of the possibility of instant attacks under 

present circumstances. Opinion on the subject is divided. Those who claim the 

existence of the right say that the phrase “if an armed attack occurs” is not 

exclusive. This is reminiscent of the view that protection of “vital interests” 

justifies the use of force. In practical terms, however, states do not invoke the right 

because they are afraid that it might be used against them too. Practice on the

subject is inconclusive. It will be recalled that Israel launched a preemptive strike 

against its Arab neighbors in 1967 but the United Nations did not condemn the 

act. The Nicaragua case, even with its extensive discussion of self defense, did not 

mention anticipatory self-defense.

In the case of the Gulf War against Iraq, the Allied forces came on invitation 

of Kuwait which was under invasion. The right to use force to defend claimed 

territory was rejected in the Falkland war.

CHAPTER 14

THE USE OF FORCE SHORT OF WAR

301

An interesting development in the wake of the September 21 attack on the 

World Trade Center is that Article 51 seems to have been used to justify a 

response against a non-state aggressor. The coalition of forces which joined the 

United States in the attacks on Afghanistan had the blessing of the General

Assembly, the Security Council, and of NATO.

Traditionally Allowable Coercive Measures.

Under international law, certain forms of coercive measures or “self help” 

have been traditionally allowed. These include: Since there is no obligation to 

maintain diplomatic relations, severance of diplomatic relations is not prohibited. 

However, this should not be resorted to unless truly necessary because severance 

might endanger peace. Moreover, severance should be distinguished from 

suspension of diplomatic relations. Suspension involves withdrawal of diplomatic 

representation but not of consular representation.

Retorsion is any of the forms of counter-measures in response to an 

unfriendly act. Forms of retorsion include shutting of ports to vessels of an 

unfriendly state, revocation of tariff concessions not guaranteed by treaty, or the 

display of naval forces near the waters of an unfriendly state.

Reprisal denotes any kind of forcible or coercive measures whereby one 

State seeks to exercise a deterrent effect or obtain redress or satisfaction, directly 

or indirectly, for the consequences of the illegal at of another state which has 

refused to make amends for such illegal acts. Unlike retorsion, the acts, standing 

by themselves, would normally be illegal. Moreover, reprisal must be preceded by 

an unsatisfied demand for reparation.

Under the Charter, however, reprisals have been narrowed down especially 

since situations likely to cause disruption of peace should be brought to the 

Security Council.

Embargo is another lawful measure. This can consist of seizure of vessels 

even in the high seas. Embargo might also be pacific, as when a state keeps its 

own vessels for fear that it might find their way in foreign territory. Their can also 

be collective embargo, e.g., on import of drugs or of oil.

Boycott is a form of reprisal which consists of suspension of trade or 

business relations with the nationals of an offending state.

302 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Some claim that this is a form of economic aggression which should be prohibited 

by law.

Non-intercourse consists of suspension of all commercial intercourse with a 

state.

Pacific blockade is a naval operation carried out in time of peace whereby a 

state prevents access to or exit from particular ports or portions of the coast of 

another state for the purpose of compelling the latter to yield to demands made by 

the blockading state.

It is essentially a warlike act and therefore frowned upon by the UN 

Charter.

These measures, to the extent that they have not been outlawed by the 

Charter, may be employed by individual states or by collective action under the 

UN.

Protection of Nationals Abroad.

Those who assert the right to defend nationals abroad argue that the right to

protect nationals abroad can be defended as an aspect of the right to self-defense 

in Article 51 since population is an essential element of statehood. Others argue 

that Article 2(4) does not prohibit it because it does not compromise the 

“territorial integrity or political independence” of a state.

Examples of forcible rescue of nationals are the raid of Entebee in Uganda 

and the US intrusion into Stanleyville to rescue American students. But the

legitimacy of such intervention is not firmly established in international law.

Humanitarian Intervention.

Discussion of armed humanitarian intervention by states in response to 

massive violation of human rights in another state begins with the prohibition of 

force in Article 2(4). The prohibition is now considered jus cogens. The prevailing 

opinion is that intervention without the authorization of the Security Council 

violates international law. One author describes the circumstances allowing 

humanitarian intervention thus:5

5Bruno Simma, NATO, The UN and the Use of Force: Legal Aspects, 10 Eur. J InT’l L,

No. 1.

CHAPTER 14

THE USE OF FORCE SHORT OF WAR

303

The question of the legality versus the illegality of so-called 

“humanitarian intervention” must be answered in light of the foregoing. Thus, if the Security Council determines that massive violations of human rights occurring within a country constitute a threat to 

the peace, and then calls for or authorizes an enforcement action to 

put an end to these violations, a “humanitarian intervention” by 

military means is permissible. In the absence of such authorization, 

military coercion employed to have the target state return to a respect 

for human rights constitutes a breach of Article 2(4) of the Charter. 

Further, as long as humanitarian crises do not transcend borders, as it 

were, and lead to armed attacks against other states, recourse to 

Article 51 is not available. For instance, a mass exodus of refugees 

does not qualify as an armed attack. In the absence of any justification 

unequivocally provided by the Charter “the use of force could not be 

the appropriate method to monitor or ensure ... respect [for human 

rights],” to use the words of the International Court of Justice in its 

1986 Nicaragua judgment. In the same year, the United Kingdom 

Foreign Office summed up the problems of unilateral, that is, 

unauthorized, humanitarian intervention as follows:

the overwhelming majority of contemporary legal opinion 

comes down against the existence of a right of humanitarian 

intervention, for three main reasons: firstly, the UN Charter and 

the corpus of modem international law do not seem to 

specifically incorporate such a right; secondly, State practice in 

the past two centuries, and especially since 1945, at best 

provides only a handful of genuine cases of humanitarian 

intervention, and, on most assessments, none at all; and finally, 

on prudential grounds, that the scope for abusing such a right 

argues strongly against its creation.... In essence, therefore, the 

case against making humanitarian intervention an exception to 

the principle of non-intervention is that its doubtful benefits 

would be heavily outweighed by its costs in terms of respect for 

international law.

The same author, however, asks whether perhaps the law on the subject has

changed under the shock of genocide and crimes against humanity. He concludes:

By way of conclusion to this section: whether we regard the 

NATO threat employed in the Kosovo crisis as an ersatz Chapter VII 

measure, “humanitarian intervention,” or as a threat of collective 

countermeasures involving armed force, any attempt at

304 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

legal justification will ultimately remain unsatisfactory. Hence, we

would be well advised to adhere to the view emphasized and 

affirmed so strongly in the German debate, and regard the Kosovo 

crisis as a singular case in which NATO decided to act without 

Security Council authorization out of overwhelming humanitarian 

necessity, but from which no general conclusion ought to be drawn. 

What is involved here is not legalistic hair-splitting versus the pursuit 

of humanitarian imperatives. Rather, the decisive point is that we 

should not change the rules simply to follow our humanitarian 

impulses; we should not set new standards only to do the right thing 

in a single case. The legal issues presented by the Kosovo crisis are

particularly impressive proof that hard cases make bad law.

Another author, while basically adhering to the legal conclusion above, does 

not stop there. He says:6

Be that as it may, any person of common sense is justified in 

asking him or herself the following dramatic question: Faced with 

such an enormous human-made tragedy and given the inaction of the 

UN Security Council due to the refusal of Russia and China to 

countenance any significant involvement by the international 

community to stop the massacres and expulsions, should one sit idly 

by and watch thousands of human beings being slaughtered or 

brutally persecuted? Should one remain silent and inactive only 

because the existing body of international law proves incapable of 

remedying such a situation? Or, rather, should respect for the Rule of 

Law be sacrificed on the altar of human compassion?

My answer is that from an ethical viewpoint resort to armed 

force was justified. Nevertheless, as a legal scholar I cannot avoid 

observing in the same breath that this moral action is contrary to 

current international law.

I contend, however, that as legal scholars we must stretch our 

minds further and ask ourselves two questions. First, was the NATO 

armed intervention at least rooted in and partially justified by 

contemporary trends of the international community? Second, were 

some parameters set, in this particular instance of use of force, that 

might lead to a gradual legitimation of forcible humanitarian 

countermeasures by a group of states outside any authorization by the 

Security Council?

COUNTERMEASURES IN THE WORLD COMMUNITY. 10 Eur. J Int’l L, No. 1.

CHAPTER 14

THE USE OF FORCE SHORT OF WAR

Based on these nascent trends in the world community, I 

submit that under certain strict conditions resort to armed force may 

gradually become justified, even absent any authorization by the 

Security Council. These conditions may be enumerated as follows:

(i) gross and egregious breaches of human rights 

involving loss of life of hundreds or thousands of innocent 

people, and amounting to crimes against humanity, are carried 

out on the territory of a sovereign state, either by the central 

governmental authorities or with their connivance and support, 

or because the total collapse of such authorities cannot impede 

those atrocities; (ii) if the crimes against humanity result from 

anarchy in a sovereign state, proof is necessary that the central 

authorities are utterly unable to put an end to those crimes, 

while at the same time refusing to call upon or to allow other 

states or international organizations to enter the territory to 

assist in terminating the crimes. If, on the contrary, such crimes 

are the work of the central authorities, it must be shown that 

those authorities have consistently withheld their cooperation 

from the United Nations or other international organizations, or 

have systematically refused to comply with appeals, 

recommendations or decisions of such organizations; (iii) the 

Security Council is unable to take any coercive action to stop 

the massacres because of disagreement among the Permanent

Members or because one or more of them exercises its veto 

power. Consequently, the Security Council either refrains from 

any action or only confines itself to deploring or condemning 

the massacres, plus possibly terming the situation a threat to the 

peace; (iv) all peaceful avenues which may be explored 

consistent with the urgency of the situation to achieve a 

solution based on negotiation, discussion and any other means 

short of force have been exhausted, notwithstanding which, no 

solution can be agreed upon by the parties to the conflict; (v) a 

group of states (not a single hegemonic Power, however strong 

its military, political and economic authority, nor such a Power 

with the support of a client state or an ally) decides to try to halt 

the atrocities, with the support or at least the nonopposition of 

the majority of Member States of the UN; (vi) armed force is 

exclusively used for the limited purpose of stopping the 

atrocities and restoring respect for human

306 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

rights, not for any goal going beyond this limited purpose. 

Consequently, the use of force must be discontinued as soon as 

this purpose is attained. Moreover, it is axiomatic that use of 

force should be commensurate with and proportionate to the 

human rights exigencies on the ground. The more urgent the 

situation of killings and atrocities, the more intensive and 

immediate may be the military response thereto. Conversely, 

military action would not be warranted in the case of a crisis 

which is slowly unfolding and which still presents avenues for 

diplomatic resolution aside from armed confrontation.

Despite all these possible shortcomings, I believe that it is our 

task as international lawyers to pinpoint the evolving trends as they 

emerge in the world community, while at the same time keeping a 

watchful eye on the actual behaviour of states. Standards of conduct 

designed to channel the action of states are necessary in the world 

community as in any human society. And it is not an exceptional 

occurrence that new standards emerge as a result of a breach of lex 

lata. To suggest realistic but prudent parameters in line with the 

present trends in the world community might serve the purpose of 

restraining as much as possible recourse to armed violence in a 

community that is increasingly bent on conflict and bloodshed.

Chapter 15

THE LAW OF WAR (INTERNATIONAL 

HUMANITARIAN LAW)

International Humanitarian Law.

What used to be known as the Laws of War now come under what is called 

International Humanitarian Law. It provides for instances when the use of armed 

force is justifiable (jus ad be Hum) and it regulates the conduct of armed conflict 

(jus in bello).

Hyde, writing in 1922, said: “It always lies within the power of a State ... to 

gain political or other advantages over another, not merely by the employment of 

force, but also by direct recourse to war.” Early international law did not consider 

as illegal a war admittedly waged for such purposes. It rejected, to that extent, the 

distinction between just and unjust wars. War was in law a natural function of the 

State and a prerogative of its uncontrolled sovereignty.

There were early attempts to outlaw war such as in the Hague Convention II 

(1907), in the Covenant of the League of Nations (1919), and in the Kellog-Briand 

Pact for the Renunciation of War (1928). But these did not prevent the horrors of 

World War II. It was after World War II that a more effective law on preventing 

war was formulated.

Article 2(4) of the UN Charter says: “All Members shall refrain in their 

international relations from the threat or use of force against the territorial integrity 

or political independence of any state, or in any other manner inconsistent with the 

Purposes of the United Nations.” In effect, this provision outlaws war.

The paradox, however, is that side by side with the prohibition of armed 

conflict is the proliferation of laws of war. Three facts can explain the paradox: 

first, those who resort to the use of arms do not give up until they have achieved 

victory; second, given the first fact, humanitarian considerations dictate the need 

for rules which curtail

307

308 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

violence beyond what is necessary to achieve a state’s goal; third, there still 

remains in the hearts of the soldiery an acceptance of chivalry as a value.

On the assumption that wars can always occur there arose the need to 

formulate laws that can humanize the conduct of war. From the middle of the last 

century the law on the area developed as a result of the pioneering effort of Henry 

Dunant who had been appalled by the brutality of the battle of Solferino. His book 

“A Memory of Solferino” inspired the cretion of the International Red Cross in 

1863 and his ideas found their way into the 1864 Geneva Convention.

The Hague Law.

Early laws of war were customary. At present the laws are largely 

conventional. In 1899, twenty-six countries met at The Hague and promulgated 

Conventions and Declaration. More conferences were held in 1907. The principles 

adopted in these conferences constitute that part of the law of armed conflict still 

known as the Law of the Hague governing land and naval warfare. Principles

governing the conduct of air warfare were to follow later.

The Geneva Conventions of 1949.

One of the most significant developments in the law of armed conflicts was 

the adoption in 1949 of four Geneva “Red Cross” Conventions governing: I —

Wounded and Sick in the Field; II — Wounded, Sick and Shipwrecked at Sea; III 

— Prisoners of War; IV — Civilians. The Convention on civilians is completely 

new and is the result of the experience of civilians in occupied territory during 

World War II.

The essence of the Geneva conventions is that persons not actively engaged 

in warfare should be treated humanely. The rules apply to any international armed 

conflict, whether a declared war or not.

Customary and Conventional Law.

Much of what is embodied in the Hague and Geneva Conventions are 

customary law. Thus, non-parties to the Convention are covered by the customary 

law of armed conflict. It has in fact become common practice, when one of the 

parties to the conflict is not a party to the conventions, for such party to make a 

declaration that it will abide

CHAPTER 15

THE LAW OF WAR

309

by the terms of the Convention. Japan, for instance, did just that at the outbreak of 

the Pacific War.

Commencement and Termination of Hostilities

Under the Hague Convention III, for an armed conflict to be considered a 

war in a legal sense, the hostilities should be preceded by a declaration of war or 

an ultimatum with a fixed limit. Since 1939, however, most armed conflicts have 

commenced without a declaration or ultimatum. With the exception of the attack 

on Poland, Germany’s attack on other states was done without benefit of 

declaration. So was Japan’s attack on Pearl harbor. Thus, while the Constitution 

gives to the legislature the power to declare the existence of a state of war and to 

enact all measures to support the war, the actual power to make war is lodged 

elsewhere, that is, in the executive power which holds the sword of the nation. The 

executive power, when necessary, may make war even in the absence of a 

declaration of war. In the words of the American Supreme Court, war being a 

question of actualities, “the President was bound to meet it in the shape it 

presented itself, without waiting for Congress to baptize it with a name; and no 

name given to it by him or them could change the fact.”1

For that matter, as far as 

the UN Charter is concerned, there is no provision requiring a declaration of war 

or an ultimatum. Normally, however, the victims of the attack respond with a 

declaration of war.

The commencement of hostilities result in the severance of all normal

relations. Political and economic treaties are terminated. However, treaties of a 

humanitarian character remain in force.

Nationals of a combatant state residing in enemy territory become subject to 

restrictions which the enemy might impose subject to limitations found in 

customary or treaty law. Merchant vessels found in enemy territory are given a 

period of grace to depart.

The laws of armed conflict remain in effect until the conflict is terminated. 

There is some conflict as to when armed conflict actually ends. But the clearest 

method of termination is by means of a peace treaty. Nevertheless, even in the 

absence of a peace treaty, once the combatant states have made a declaration that 

hostilities have come to an end, the armed forces are bound by such declaration.

'See Prize Cases, 2 Bl. 635 (U.S. 1863).

310 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Armistice, however, which is an agreement to suspend hostilities, whether 

local or general, does not end the conflict. But it puts an end to active fighting in 

accordance with the terms of the agreement.

Protocol I

Protocol I to the 1949 Geneva Convention created a new category of 

international armed conflict. It includes within the definition of international 

armed conflict

armed conflicts in which peoples are fighting against colonial 

domination and alien occupation and against racist regimes in the 

exercise of their right of self-determination, as enshrined in the 

Charter of the United Nations and the Declaration on Principles of 

International Law concerning Friendly Relations and Co-operation 

among States in accordance with the Charter of the United Nations.

Those engaged in such a conflict receive combatant status and are entitled 

to combatant rights and duties. For instance, when captured, they are not to be 

treated as ordinary criminals but as prisoners of war.

Methods of Warfare: Jus in Bello.

The purpose of the laws on armed conflict is well expressed by the 

nineteenth century Declaration of St. Petersburg which said:

The progress of civilization should have the effect of alleviating as much as possible the calamities of war: the only legitimate 

object which states should endeavour to accomplish during war is to 

weaken the military forces of the enemy; for this purpose it is 

sufficient to disable the greatest possible number of men; this object 

would be exceeded by the employment of arms which uselessly 

aggravate the sufferings of disabled men, or render their death 

inevitable; the employment of such arms would, therefore, be 

contrary to the laws of humanity.

Thus, it is that the Hague Convention prohibits the employment of “arms, 

projectiles or material calculated to cause unnecessary suffering.” There is a need 

to balance military necessity and humanitarian consideration. This is also 

expressed in the advisory opinion on the Legality of the Threat or Use of Nuclear 

Weapons (ICJ 1996):

CHAPTER 15

THE LAW OF WAR

311

The cardinal principles contained in the texts constituting the 

fabric of humanitarian law are the following. The first is aimed at the 

protection of the civilian population and civilian objects and 

establishes the distinction between combatants and non- combatants; 

states much never make civilians the object of attack and must 

consequently never use weapons that are incapable of distinguishing 

between civilian and military targets. According to the second 

principle, it is prohibited to cause unnecessary suffering to 

combatants; its is accordingly prohibited to use weapons causing 

them such harm or uselessly aggravating their suffering.

In application of that second principle, states do not have unlimited 

freedom of choice of means in the weapons they use.

The International Commission of the Red Cross published three statements 

which sum up the basic rules governing armed conflicts:2

I. The Soldier’s Rules

1. Be a disciplined soldier. Disobedience of the laws of war 

dishonours your army and yourself and causes unnecessary suffering; 

far from weakening the enemy’s to fight, it often strengthens it.

2. Fight only enemy combatants and attack only military 

objectives.

3. Destroy no more than your mission requires.

4. Do not fight enemies who are ‘out of combat’ [hors de 

combat] or surrender. Disarm them and hand them over to your 

superior.

5. Collect and care for the wounded and sick, be they friend 

or foe.

6. Treat all civilians and all enemies in your power with 

humanity.

7. Prisoners of war must be treated humanely and are bound 

to give only information about their identity. No physical or mental

torture of prisoners of war is permitted.

8. Do not take hostages.

9. Abstain from all acts of vengeance.

2

See L.C. Green, THE CONTEMPORARY LAW OF ARMED CONFUCT, Manchester University Press,

(1993).

312 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

10. Respect all persons objects bearing the emblem of the 

red cross, red crescent, red lion and sun, the white flag of truce or 

emblems designating cultural property.

11.

espect other people’s property. Looting is prohibited.

12.

ndeavour to prevent any breach of the above rules. Report any 

violation to your superior. Any breach of the law of war is 

punishable.

II. Fundamental Rules of International Humanitarian Law 

Applicable to Armed Conflicts

1. Persons hors de combat and those who do not take a 

direct part in hostilities are entitled to respect for their lives and moral 

and physical integrity. They shall in all circumstances be protected 

and treated humanely without any adverse distinctions.

2. It is forbidden to kill or injure an enemy who surrenders 

or is hors de combat.

3.

he wounded and sick shall be collected and cared for by the party to 

the conflict which has them in its power. Protection also covers 

medical personnel, establishments, transports and equipment. The 

emblem of the red cross or the red crescent is the sign of such 

protection and must be protected.

4. Captured combatants and civilians under the authority of 

an adverse party are entitled to respect for their lives, dignity, 

personal rights and convictions. They shall be protected against all 

acts of violence and reprisals. They shall have the rights to correspond with their families and receive relief.

5. Everyone shall be entitled to benefit from fundamental 

judicial guarantees. No one shall be responsible for an act he has not 

committed. No one shall be subjected to physical and mental torture, 

corporal punishment or cruel or degrading treatment.

6. Parties to a conflict and members of their armed forces 

do not have an unlimited choice of methods and means of warfare. It 

is prohibited to employ weapons or methods of warfare of a nature to 

cause unnecessary losses or excessive suffering.

7. Parties to a conflict shall at all times distinguish between 

the civilian population and combatants in order to spare civilian 

population and property. Neither the civilian population as such nor 

civilian persons shall be the object of attack. Attacks shall be directed 

only against military objectives.

CHAPTER 15

THE LAW OF WAR

III. Non-International Armed Conflicts

A. General Rules

1. The obligation to distinguish between combatants and 

civilians is a general rule applicable in non-international armed 

conflicts. It prohibits indiscriminate attacks.

2. The prohibition of attacks against the civilian population 

as such or against individual civilians is a general rule applicable in 

non-international conflicts. Acts of violence in tended primarily to 

spread terror among the civilian population are also prohibited.

3. The probation of superfluous injury or unnecessary 

suffering is a general rule applicable in non-international conflicts. It 

prohibits, in particular, the use of means of warfare which uselessly 

aggravate the sufferings of disabled men or render their death 

inevitable.

4. The prohibition to kill, injure or capture an adversary by 

resort to perfidy is a general rule applicable in non-international 

armed conflicts; in a non-international armed conflict, acts inviting 

the confidence of an adversary to lead him to believe that he is 

entitled to, or is obliged to accord protection under the rules of 

international law applicable in non-international armed conflicts, with 

intent to betray that confidence, shall constitute perfidy.

5. The obligation to respect and protect medical and religious personnel and medical units and transports in the conduct of 

military operations is a general rule applicable in non-international 

armed conflicts.

6. The general rule prohibiting attacks against the civilian 

population implies, as a corollary, the prohibition of attacks on 

dwellings and other installations which are used only by the civilian 

population.

7. The general rule prohibiting attacks upon the civilian 

population implies, as a corollary, the prohibition to attack, destroy, 

remove or render useless objects indispensable to the survival of the 

civilian population.

8. The general rule to distinguish between combatants and 

civilians and the prohibition of attacks against the civilian population 

as such or against individual civilians implies, in order to be effective, 

that all feasible precautions have to be taken to avoid injury, loss or 

damage to the civilian population.

314 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

B. Prohibitions and Restrictions on the Use of Certain Weapons

1. The customary rule prohibiting the use of chemical 

weapons, such as those containing asphyxiating or vesicant agents, 

and the use of bacteriological (bacterial) weapons is applicable in 

non-international armed conflicts.

2. The customary rule prohibiting bullets which expand or 

flatten easily in the human body, such as Dum-Dum bullets, is 

applicable in non-international armed conflicts.

3. The customary rule prohibiting the use of poison as a 

means of warfare is applicable in non-international armed conflicts.

4. In application of the general rules listed in section A 

above, especially those on the distinction between combatants and 

civilians and on the immunity of the civilian population, mines, 

booby-traps and other devices within the meaning of Protocol

II to the 1980 Convention on conventional weapons may not be 

directed against the civilian population as such or against individual 

civilians, nor used indiscriminately.

The prohibition of booby-traps listed in Article 6 of the 

Protocol extends to their use in non-international armed conflicts, in 

application of the general rules on the distinction between combatants 

and civilians, the immunity of the civilian population, the prohibition 

of superfluous injury or unnecessary suffering, and the prohibition of

perfidy.

To ensure the protection of the civilian population referred to in 

the previous paragraphs, precaution must be taken to protect it from 

attacks in the form of mines, booby-traps and other devices.

5. In application of the general rules listed in section A 

above, especially those on the distinction between combatants and 

civilians and on the immunity of the civilian population, incendiary 

weapons may not be directed against the civilian population as such, 

against individual civilians or civilian objects, nor used 

indiscriminately.

Neutrality.

In a conflict among various powers, there are always some who prefer to 

stay out of the fray. They adopt an attitude of impartiality towards the belligerents.

Such an attitude must be recognized by belligerents and creates both rights and 

duties in the neutral states. The

CHAPTER 15

THE LAW OF WAR

315

decision to adopt or not to adopt a neutral stance is not governed by international 

law. It is a dictated by politics. For that reason, there is no special mode of 

assertion required.

Belligerents must respect the rights of neutral states. For their part, neutrals 

must not engage in activities which interfere with the activities of the belligerents. 

The detailed rules concerning the rights and duties of neutrals and belligerents are 

found in Hague Convention V, 1907.

Non-international conflicts.

Civil wars

Civil wars or rebellion do not violate international law. Article 2(4) of the 

Charter does not apply to internal conflicts.

Outside help for governments experiencing rebellion is generally considered 

legitimate provided requested by the government. However, there is no total 

clarity in this matter especially in situations were the rebels may be on the verge of 

gaining victory.

Aid to rebels is contrary to international law. The 1970 Declaration on 

Principles of international law says that “no state shall organize, assist, foment, 

finance, incite or tolerate subversive, terrorist or armed activities directed towards 

the violent overthrow of the regime of another state, or interfere in civil strife in 

another state.”

Common Article 3

Traditionally, international law on armed conflict does not apply to internal 

conflicts such as civil wars or rebellions. In 1949, however, it was decided that 

minimum humanitarian protection should also be promulgated to cover internal 

conflict. For this reason, each of the four Geneva Conventions contains a common 

Article 3 which says:

Art. 3. In the case of armed conflict not of an international 

character occurring in the territory of one of the High Contracting 

Parties, each Party to the conflict shall be bound to apply, as a 

minimum, the following provisions:

(1) Persons taking no active part in the hostilities, including 

members of armed forces who have laid down their arms and those 

placed hors de combat by sickness, wounds, detention, or any other 

cause, shall in all circumstances be treated humanely,

3)6 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

without any adverse distinction founded on race, colour, religion or 

faith, sex, birth or wealth, or any other similar criteria.

To this end, the following acts are and shall remain prohibited 

at any time and in any place whatsoever with respect to the abovementioned persons:

(a) violence to life and person, in particular murder of 

all kinds, mutilation, cruel treatment and torture;

(b) taking of hostages;

(c) outrages upon personal dignity, in particular humiliating and degrading treatment;

(d) the passing of sentences and the carrying out of 

executions without previous judgment pronounced by a regularly constituted court, affording all the judicial guarantees 

which are recognized as indispensable by civilized peoples.

(2) The wounded and sick shall be collected and cared for.

An impartial humanitarian body, such as the International 

Committee of the Red Cross, may offer its services to the Parties to 

the conflict.

The Parties to the conflict should further endeavour to bring 

into force, by means of special agreements, all or part of the other 

provisions of the present Convention.

The application of the preceding provisions shall not affect the 

legal status of the Parties to the conflict.

The last sentence means that the application does not convert the conflict 

into an international one and therefore does not preclude the possibility that any 

participant in the conflict may be prosecuted for treason.

Protocol II

The first and only international agreement exclusively regulating the 

conduct of parties in a non-international armed conflict is the 1977 Protocol II to 

the 1949 Geneva Conventions. It “develops and supplements Article 3 common to 

the Geneva Conventions of 12 August 1949 without modifying its existing 

conditions or application.” A non-international armed conflict covered by this 

expanded guarantee is defined in Article I. They are armed conflicts — 

CHAPTER 15

THE LAW OF WAR

317

which take place in the territory of a High Contracting Party between 

its armed forces and dissident armed forces or other organized armed 

groups which, under responsible command, exercise such control 

over a part of its territory as to enable them to carry out sustained and 

concerted military operations and to implement this Protocol.

Article I further adds that the “Protocol shall not apply to situations of 

internal disturbances and tensions, such as riots, isolated and sporadic acts of 

violence and other acts of a similar nature, as not being armed conflicts.” This is 

true even if the armed forces of the territory may have been called upon to 

suppress the disorder.

It will thus be seen that Protocol II sets down requirements for what it calls 

“material field of application.” First, the armed dissidents must be under 

responsible command; second, they must “exercise such control over a part of its 

territory as to enable them to carry out sustained and concerted military operations 

and to implement this Protocol.” The Protocol thus sets a very high threshold for 

applicability, higher than the threshold for the applicability of Protocol I which 

does not require control over territory. For this reason, in the conflict between the 

Philippine government and the National Democratic Front, the Philippine 

government has been able to maintain consistently that the NDF and its New 

People’s Army have not crossed this threshold and that therefore what applies to 

them is Common Article 3.

International Terrorism.

There is no crime named terrorism in Philippine statute books, although 

some acts which are considered terroristic are independently punished by the 

Revised Penal Code. The U.S. has its municipal Anti- Terrorism Law 

(International Crime Control Act of 1998) and the UK has the Terrorism Act of 

2000. In the British law, what come under the Terrorism Act are violent moves 

against person or property or against public health and safety which have for their 

purpose to influence the government or to intimidate a section of the public or to 

advance a political, religious or ideological cause. The taking of hostages, indiscriminate killings or destruction of property for the enumerated purposes come 

under the law. But these can also be prosecuted as individual crimes in domestic 

law.

318 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

In international law, part of the problem in criminalizing terrorism is the 

difficulty in defining the prohibited act. A draft of an International Convention for 

the Suppression of the Financing of Terrorism adopted by the General Assembly 

of the United Nations on December 9, 1999 makes an attempt at a definition. It 

says:

Any person commits an offense [of terrorism] within the 

meaning of this Convention if that person, by any means, unlawfully 

and intentionally, does an act intended to cause (a) death or serious

bodily injury to any person, or (b) serious damage to a State or 

Government facility with the intent to cause extensive destruction of 

such a place, facility or system, or where such destruction results or is 

likely to result in major economic loss, when the purpose of such act, 

by its nature or context, is to intimidate a population, or to compel a 

Government or an international organization to do or abstain from 

doing any act.

Can it be said, however, that even now terrorism is already a crime against 

humanity covered by universal jurisdiction? The attack on the World Trade Center 

on September 11, 2001, was characterized as a crime against humanity by the 

French jurist and Minister of Justice, Robert Badinter, and likewise by Kofi 

Annan of the UN Secretariat and by Mary Robinson, the UN High Commissioner 

on Human Rights. They were followed in this by a number of distinguished jurists 

like Alain Pellet of Le Monde and the British lawyer G. Robinson. What led them 

to arrive at this conclusion was the atrocious character exhibited by the act: its 

magnitude, its gravity, the targeting of civilians seen as part of a well-planned 

operation.

A time may come when other states will follow in characterizing the act as 

a crime against humanity. But it would be necessary to determine what the 

specific conditions should be for considering an act as one against humanity. 

Obviously not every act of terrorism would have the magnitude and gravity of the 

September 11 attack.

The importance of the characterization of the September 11 attack as a

crime against humanity is that it led to what seems to be a development in the 

international law of self-defense. Under traditional international law as now 

embodied in the UN Charter, self-defense is a legitimate response to an armed 

attack by a state. But the magnitude of the attack of September 11 was such that it 

persuaded the Security Council and the North Atlantic Treaty Organization to 

issue resolutions

CHAPTER 15

THE LAW OF WAR

319

which in effect justified resort to Art. 51 of the UN Charter on collective selfdefense without waiting for action by the Security Council. A NATO press release 

agreed that an armed attack against one or more of the Allies in Europe or North 

America shall be considered an attack against them all. Thus the action of the 

various states which have joined the coalition against the forces of Bin Laden has 

assimilated the terrorist attack on the WTC to an attack by a state sufficient to 

trigger resort to collective self-defense.

If this means a development in the international law on self defense, it 

would still be necessary to deal with some problems that need clarification. For 

one, of what magnitude should the attack be to merit assimilation with an attack 

by a state? This is relevant for determining whether the activities, for instance, of 

the Abu Sayyaf, even if internationally connected, are of a magnitude to qualify as 

an “armed attack” under the terms of the Mutual Defense Treaty between the 

Philippines and the United States. Moreover, as one writer put it with regard to 

fighting terrorism, “Problems arise with regard to the target of self defense, its 

timing, its duration, and the admissible means."

The issue of target necessarily brings in the issue of sovereignty because 

presumably the targets would be found in some state territory. Furthermore, at 

what point would justifiable self-defense end? In traditional wars, this is more 

easily determined. Not so in the fight against terrorism. Finally, one would have to 

ask what means are justifiable. These questions are central to the conflict between 

Israel and Hamas of Palestine.

Chapter 16

INTERNATIONAL ENVIRONMENTAL LAW

Environmental concerns.1

Concern about the environment is expressed by the Philippine Constitution 

in Article II, Section 16 thus: “The State shall protect and advance the right of the 

people to a balanced and healthful ecology in accord with the rhythm and harmony 

of nature.” The discussions in the 1986 Constitutional Commission manifested a 

clear desire to make environmental protection and ecological balance conscious 

objects of police power.2 Oposa v. Factoran, Jr.,3

on the basis of Section 16 linked 

with the right to health, recognized a constitutional “right to a balanced and 

healthful ecology” and “the correlative duty to refrain from impairing the 

environment.”4 Oposa was followed by Laguna Lake Development Authority

(LLDA) v. Court of Appeals? The Supreme Court, relying on Section 16, as also 

bolstered by the right to health in Section

15 as well as by the Universal Declaration of Human Rights and the Alma 

Conference Declaration of 1978, upheld the authority of LLDA to protect the 

inhabitants of the Laguna Lake Area from the deleterious effects of pollutants 

coming from garbage dumping and the discharge of wastes in the area.6

Laguna 

Lake upheld the exclusive authority of the Laguna Lake Development Authority to 

regulate the exploitation of Laguna Lake, as against the claim of municipalities 

around the lake, in order to effectively address the environmental and ecological 

stress on Laguna Lake.

Along a similar vein, in 2007, the Supreme Court upheld the validity of an 

ordinance of the City of Manila requiring the oil companies to close and transfer 

the Pandacan Terminals to another location within a specified period.7

The latest 

on this subject was Metropolitan Manila Development Authority v. Residents of 

Manila Bay8 where the Supreme Court ordered various government agencies to 

clean up Manila Bay.

The protection of the environment is now also a concern of international 

law. It is in fact a challenge to the development of international law because its 

demands cannot be met without intrusion into the domestic jurisdiction and 

sovereignty of states. The nature and magnitude of the challenge are such that they 

require not only the joint action of states but also the involvement of non-state 

actors.

Environmental concerns

The concern of environmental protection is not just about the atmosphere, 

the sea, the land, flora and fauna. It is also about the preservation of the cultural 

heritage of mankind as found in archeological and artistic remains. The goal of 

environmental protectionists is the rational use of the elements that make up the 

environment through control, reduction and, wherever possible, elimination of the

causes of environmental degradation.

Inseparably related with environmental concerns are human rights issues. 

Thus the long delay of Gorbachev before issuing a statement about the danger 

posed by the Chernobyl nuclear disaster was a violation of the human rights of 

those affected by the leak. To a lesser degree it can be said that the failure of the 

government to prevent pollution of the Pasig and the failure of the Traffic Bureau 

to check offending vehicles and factories are a violations of the the people’s right 

to a healthy environment. As the ICJ pronounced in the Danube Dam Case (ICJ 

Rep. 1997): “The protection of the environment is a ... vital part of contemporary 

human rights doctrine, for it is a sine qua non for numerous human rights such as 

the right to health, and the right to life itself.”

What make the task difficult are various competing interests. In a world of 

so much poverty and exploding population, it is not possible

322 INTRODUCTION TO PUBUC INTERNATIONAL LAW

to ignore the need for poverty alleviation. Added to these are the issues of 

sovereignty and the still controversial issue of state responsibility.

Who have environmental rights?

In protecting the environment, the real objects of protection are persons 

capable of having rights. Trees and others can be said to have rights only in a 

metaphorical sense. Thus the approach in Oposa v. Factoran, Jr.9 was to have 

minors plead for “intergenerational protection,” and the right asserted was not of 

the inanimate world but of generations of people. The case involved thirty-four 

minors who went to Court represented by their parents pleading the cause of 

“intergenerational responsibility” and “inter-generational justice” and asking the 

Supreme Court to order the Secretary of Natural Resources to cancel all existing 

timber license agreements and to “cease and desist from receiving, accepting, 

processing, renewing or approving new timber license agreements.” The minors 

filed the action for themselves as representing “their generation as well as 

generations yet unborn.” The Supreme Court recognized the existence of the right. 

Although Oposa, Jr. did not order the Secretary outright to cancel licenses and 

desist from issuing new ones, the Court affirmed the justiciability of the issue

raised and remanded the case to the lower court for further proceedings.

Earlier, in the Trail Smelter Case (see Chapter 8, supra) the Arbitral 

Tribunal also said that “no state has the right to use or permit the use of its 

territory in such manner as to cause injury by fumes in or to the territory of 

another or the properties or persons therein ...” The Nuclear Test Cases, supra, was 

based on the claim that atmospheric nuclear testing was a breach of customary 

international law and would also infringe Australia’s sovereignty over its territory.

“Sustainable Development.”

An important concept in the field both of economics and environmental 

rights is the concept of sustainable development. It is a concept adopted by the 

World Commission on Environment and Development in recognition of 

competing claims of states in the areas of the preservation of the environment and 

the right to development. The concept

*225 SCRA 792 (1993).

CHAPTER 16

INTERNATIONAL ENVIRONMENTAL LAW

323

encourages development in a manner and according to methods which do not 

compromise the ability of future generation and other states to meet their needs. 

The eloquent words of Justice Douglas in Sierra Club v. MortonX0 are often 

quoted:

The voice of the inanimate object, therefore, should not be 

stilled. That does not mean that the judiciary takes over the 

management functions from the federal agency. It merely means that 

before these priceless bits of Americana (such as a valley, an alpine 

meadow, a river or a lake) are forever lost or are so transformed as to 

be reduced to the eventual rubble of our urban environment, the voice 

of the existing beneficiaries of these environmental wonders should 

be heard.

Emerging principles.

Stockholm Declaration

Various principles of environmental protection are gradually being 

developed and are coming out from various conferences. Notable is the Stockholm 

Declaration of 1972 formulated in a UN Conference on the Human Environment 

by 113 states.

The Conference calls upon Governments and peoples to exert common 

efforts for the preservation and improvement of the human environment, for the 

benefit of all the people and for their posterity.

Principles

States the common conviction that:

Principle 1

Man has the fundamental right to freedom, equality and adequate 

conditions of life, in an environment of a quality that permits a life of 

dignity and well-being, and he bears a solemn responsibility to protect and 

improve the environment for present and future generations. In this respect, 

policies promoting or perpetuating apartheid, racial segregation, 

discrimination, colonial and other forms of oppression and foreign 

domination stand condemned and must be eliminated.

10405 US 727 (1972).

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Principle 2

The natural resources of the earth, including the air, water, land, flora 

and fauna and especially representative samples of natural ecosystems, must 

be safeguarded for the benefit of present and future generations through 

careful planning or management, as appropriate.

Principle 3

The capacity of the earth to produce vital renewable resources must 

be maintained and, wherever practicable, restored or improved.

Principle 4

Man has a special responsibility to safeguard and wisely manage the 

heritage of wildlife and its habitat, which are now gravely imperilled by a 

combination of adverse factors. Nature conservation, including wildlife, 

must therefore receive importance in planning for economic development.

Principle 5

The non-renewable resources of the earth must be employed in such a 

way as to guard against the danger of their future exhaustion and to ensure 

that benefits from such employment are shared by all mankind.

Principle 6

The discharge of toxic substances or of other substances and the

release of heat, in such quantities or concentrations as to exceed the capacity 

of the environment to render them harmless, must be halted in order to 

ensure that serious or irreversible damage is not inflicted upon ecosystems. 

The just struggle of the peoples of ill countries against pollution should be 

supported.

Principle 7

States shall take all possible steps to prevent pollution of the seas by 

substances that are liable to create hazards to human health, to harm living 

resources and marine life, to damage amenities or to interfere with other 

legitimate uses of the sea.

CHAPTER 16

INTERNATIONAL ENVIRONMENTAL LAW

325

Principle 8

Economic and social development is essential for ensuring a favorable 

living and working environment for man and for creating conditions on 

earth that are necessary for the improvement of the quality of life.

Principle 9

Environmental deficiencies generated by the conditions of underdevelopment and natural disasters pose grave problems and can best be 

remedied by accelerated development through the transfer of substantial 

quantities of financial and technological assistance as a supplement to the 

domestic effort of the developing countries and such timely assistance as 

may be required.

Principle 10

For the developing countries, stability of prices and adequate earnings 

for primary commodities and raw materials are essential to environmental 

management, since economic factors as well as ecological processes must 

be taken into account.

Principle 11

The environmental policies of all States should enhance and not 

adversely affect the present or future development potential of developing 

countries, nor should they hamper the attainment of better living conditions 

for all, and appropriate steps should be taken by States and international 

organizations with a view to reaching agreement on meeting the possible 

national and international economic consequences resulting from the 

application of environmental measures.

Principle 12

Resources should be made available to preserve and improve the 

environment, taking into account the circumstances and particular 

requirements of developing countries and any costs which may emanate 

from their incorporating environmental safeguards into their development

planning and the need for making available to them, upon their request, 

additional international technical and financial assistance for this purpose.

326 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Principle 13

In order to achieve a more rational management of resources and thus 

to improve the environment, States should adopt an integrated and 

coordinated approach to their development planning so as to ensure that 

development is compatible with the need to protect and improve 

environment for the benefit of their population.

Principle 14

Rational planning constitutes an essential tool for reconciling any 

conflict between the needs of development and the need to protect and 

improve the environment.

Principle 15

Planning must be applied to human settlements and urbanization with 

a view to avoiding adverse effects on the environment and obtaining 

maximum social, economic and environmental benefits for all. In this 

respect, projects which are designed for colonialist and racist domination 

must be abandoned.

Principle 16

Demographic policies which are without prejudice to basic human 

rights and which are deemed appropriate by Governments concerned should 

be applied in those regions where the rate of population growth or excessive 

population concentrations are likely to have adverse effects on the 

environment of the human environment and impede development.

Principle 17

Appropriate national institutions must be entrusted with the task of 

planning, managing or controlling the environmental resources of States 

with a view to enhancing environmental quality.

Principle 18

Science and technology, as part of their contribution to economic and 

social development, must be applied to the identification, avoidance and 

control of environmental risks and the solution of environmental problems 

and for the common good of mankind.

CHAPTER 16

INTERNATIONAL ENVIRONMENTAL LAW

327

Principle 19

Education in environmental matters, for the younger generation as 

well as adults, giving due consideration to the underprivileged, is essential 

in order to broaden the basis for an enlightened opinion and responsible 

conduct by individuals, enterprises and communities in protecting and 

improving the environment in its full human dimension. It is also essential 

that mass media of communications avoid contributing to the deterioration 

of the environment, but, on the contrary, disseminates information of an

educational nature on the need to project and improve the environment in 

order to enable man to develop in every respect.

Principle 20

Scientific research and development in the context of environmental 

problems, both national and multinational, must be promoted in all

countries, especially the developing countries. In this connection, the free 

flow of up-to-date scientific information and transfer of experience must be 

supported and assisted, to facilitate the solution of environmental problems; 

environmental technologies should be made available to developing 

countries on terms which would encourage their wide dissemination without 

constituting an economic burden on the developing countries.

Principle 21

States have, in accordance with the Charter of the United Nations and 

the principles of international law, the sovereign right to exploit their own

resources pursuant to their own environmental policies, and the 

responsibility to ensure that activities within their jurisdiction or control do 

not cause damage to the environment of other States or of areas beyond the 

limits of national jurisdiction.

Principle 22

States shall cooperate to develop further the international law 

regarding liability and compensation for the victims of pollution and other 

environmental damage caused by activities within the jurisdiction or control 

of such States to areas beyond their jurisdiction.

328 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Principle 23

Without prejudice to such criteria as may be agreed upon by the 

international community, or to standards which will have to be determined 

nationally, it will be essential in all cases to consider the systems of values 

prevailing in each country, and the extent of the applicability of standards 

which are valid for the most advanced countries but which may be 

inappropriate and of unwarranted social cost for the developing countries.

Principle 24

International matters concerning the protection and improvement of 

the environment should be handled in a cooperative spirit by all countries, 

big and small, on an equal footing.

Cooperation through multilateral or bilateral arrangements or other 

appropriate means is essential to effectively control, prevent, reduce and 

eliminate adverse environmental effects resulting from activities conducted 

in all spheres, in such a way that due account is taken of the sovereignty and 

interests of all States.

Principle 25

States shall ensure that international organizations play a coordinated, 

efficient and dynamic role for the protection and improvement of the 

environment.

Principle 26

Man and his environment must be spared the effects of nuclear 

weapons and all other means of mass destruction. States must strive to reach 

prompt agreement, in the relevant international organs, on the elimination 

and complete destruction of such weapons.

21st plenary meeting

16 June 1972

Rio Declaration

In 1992, the United Nations Conference on Environment and Development 

sponsored another conference in Brazil It was attended

CHAPTER 16

INTERNATIONAL ENVIRONMENTAL LAW

329

by 170 states. The Conference came out with the Rio Declaration. The following 

principles were enunciated:

Principle I

Human beings are at the centre of concerns for sustainable 

development. They are entitled to a healthy and productive life in harmony 

with nature.

Principle 2

States have, in accordance with the Charter of the United Nations and 

the principles of international law, the sovereign right to exploit their own 

resources pursuant to their own environmental and developmental policies, 

and the responsibility to ensure that activities within their jurisdiction or 

control do not cause damage to the environment of other States or of areas 

beyond the limits of national jurisdiction.

Principle 3

The right to development must be fulfilled so as to equitably meet 

developmental and environmental needs of present and future generations.

Principle 4

In order to achieve sustainable development, environmental 

protection shall constitute an integral part of the development process and 

cannot be considered in isolation from it.

Principle 5

All States and all people shall cooperate in the essential task of 

eradicating poverty as an indispensable requirement for sustainable 

development, in order to decrease the disparities in standards of living and 

better meet the needs of the majority of the people of the world.

Principle 6

The special situation and needs of developing countries, particularly 

the least developed and those most environmentally vulnerable, shall be

given special priority. International actions in

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

the field of environment and development should also address the interests 

and needs of all countries.

Principle 7

States shall cooperate in a spirit of global partnership to conserve, 

protect and restore the health and integrity of the Earth’s ecosystem. In view 

of the different contributions to global environmental degradation, States 

have common but differentiated responsibilities. The developed countries 

acknowledge the responsibility that they bear in the international pursuit of 

sustainable development in view of the pressures their societies place on the 

global environment and of the technologies and financial resources they 

command.

Principle 8

To achieve sustainable development and a higher quality of life for all 

people, States should reduce and eliminate unsustainable patterns of 

production and consumption and promote appropriate demographic policies.

Principle 9

States should cooperate to strengthen endogenous capacity building 

for sustainable development by improving scientific understanding through 

exchanges of scientific and technological knowledge, and by enhancing the 

development, adaptation, diffusion and transfer of technologies, including 

new and innovative technologies.

Principle 10

Environmental issues are best handled with the participation of all 

concerned citizens, at the relevant level. At the national level, each 

individual shall have appropriate access to information concerning the 

environment that is held by public authorities, including information on 

hazardous materials and activities in their communities, and the opportunity 

to participate in decisionmaking processes. States shall facilitate and 

encourage public awareness and participation by making information widely 

available. Effective access to judicial and administrative proceedings, 

including redress and remedy, shall be provided.

CHAPTER 16

INTERNATIONAL ENVIRONMENTAL LAW

331

Principle 11

States shall enact effective environmental legislation. Environmental 

standards, management objectives and priorities should reflect the 

environmental and developmental context to which they apply. Standards 

applied by some countries may be inappropriate and of unwarranted 

economic and social cost to other countries, in particular developing 

countries.

Principle 12

States should cooperate to promote a supportive and open international economic system that would lead to economic growth and 

sustainable development in all countries, to better address the problems of 

environmental degradation. Trade policy measures for environmental

purposes should not constitute a means of arbitrary or unjustifiable 

discrimination or a disguised restriction on international trade. Unilateral 

actions to deal with environmental challenges outside the jurisdiction of the 

importing country should be avoided. Environmental measures addressing 

trans-boundary or global environmental problems should, as far as possible, 

be based on an international consensus.

Principle 13

States shall develop national law regarding liability and compensation 

for the victims of pollution and other environmental damage. States shall 

also cooperate in an expeditious and more determined manner to develop 

further international law regarding liability and compensation for adverse 

effects of environmental damage caused by activities within their 

jurisdiction or control to areas beyond their jurisdiction.

Principle 14

States should effectively cooperate to discourage or prevent the 

relocation and transfer to other States of any activities and substances that 

cause severe environmental degradation or are found to be harmful to 

human health.

Principle 15

In order to protect the environment, the precautionary approach shall 

be widely applied by States according to their

332 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

capabilities. Where there are threats of serious or irreversible damage, lack 

of full scientific certainty shall not be used as a reason for postponing costeffective measures to prevent environmental degradation.

Principle 16

National authorities should endeavour to promote the internalization 

of environmental costs and the use of economic instruments, taking into 

account the approach that the polluter should, in principle, bear the cost of 

pollution, with due regard to the public interest and without distorting 

international trade and investment.

Principle 17

Environmental impact assessment, as a national instrument, shall be 

undertaken for proposed activities that are likely to have a significant

adverse impact on the environment and are subject to a decision of a 

competent national authority.

Principle 18

States shall immediately notify other States of any natural disasters or 

other emergencies that are likely to produce sudden harmful effects on the 

environment of those States. Every effort shall be made by the international 

community to help States so afflicted.

Principle 19

States shall provide prior and timely notification and relevant 

information to potentially affected States on activities that may have a 

significant adverse trans-boundary environmental effect and shall consult 

with those States at an early stage and in good faith.

Principle 20

Women have a vital role in environmental management and 

development. Their full participation is therefore essential to achieve 

sustainable development.

CHAPTER 16

INTERNATIONAL ENVIRONMENTAL LAW

333

Principle 21

The creativity, ideals and courage of the youth of the world should be 

mobilized to forge a global partnership in order to achieve sustainable 

development and ensure a better future for all.

Principle 22

Indigenous people and their communities and other local 

communities have a vital role in environmental management and 

development because of their knowledge and traditional practices. States 

should recognize and duly support their identity, culture and interests and 

enable their effective participation in the achievement of sustainable 

development.

Principle 23

The environment and natural resources of people under oppression, 

domination and occupation shall be protected.

Principle 24

Warfare is inherently destructive of sustainable development. States 

shall therefore respect international law providing protection for the 

environment in times of armed conflict and cooperate in its further

development, as necessary.

Principle 25

Peace, development and environmental protection are interdependent 

and indivisible.

Principle 26

States shall resolve all their environmental disputes peacefully and by 

appropriate means in accordance with the Charter of the United Nations.

Principle 27

States and people shall cooperate in good faith and in a spirit of 

partnership in the fulfillment of the principles embodied in this Declaration 

and in the further development of international law in the field of 

sustainable development.

334 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

Some treaties

The Stockholm and the Rio Declarations are just that, declarations. They do 

not have the force of law. There exist, however, some conventions which are 

legally binding on the parties. Some of these are:

In Articles 192-194 of the 1982 LOS there are prohibitions on marine 

pollution.

The Vienna Convention for the Protection of the Ozone Layer of 1985 adopt 

various measures for the protection of the “ozone layer,” the layer of atmospheric 

ozone above the planetary boundary layer.

The United Nations Conference on Environment and Development, 1992, 

seeks to achieve “stabilization of greenhouse gas concentration in the atmosphere 

at a level that would prevent dangerous anthropogenic interference with the 

climate system.”

The Kyoto Protocol, already ratified by 84 States as of 1 November 1999, 

also seeks to protect the atmosphere.

There is also a Convention on International Trade in Endangered Species of 

Wild Fauna and Flora, 1973, and also a Convention on Biological Diversity, 1992.

There are also regional conventions involving environmental matters such 

as the Treaty of Rome of 1957 (European Union), a 1994 North American 

Agreement on Environmental Cooperation, a 1991 Protocol on Environmental 

Protection to the Antarctic Treaty of 1991, and the Amazon Declaration of 1989.

Chapter 17 INTERNATIONAL ECONOMIC LAW

What is international economic law?

Recent developments have made international economic law a distinct part 

of international law. Beyond the regulation of interstate trade, the law has moved 

into the creation of international institutions, formulation of definite rules 

governing a wide range of economic matters, and the establishment of methods of 

dispute resolution. Moreover, international economic law affects not only states 

but also multi-national corporations. Likewise, globalization of economic matters

have affected traditional notions of sovereignty.

It can thus be seen that international economic law can involve a broad 

range of transactions, regulations and litigation which cannot be adequately 

reflected in one definitional formula. As one writer has noted, ninety percent of 

international law activity is economic international law although it does not have 

the glamour of such subjects as use of force, human rights, or intervention. The 

(Third) restatement of Foreign Relations Law has this statement: “The law of 

international economic relations in its broadest sense includes all the international 

law and international agreements governing economic transactions that cross state 

boundaries or that otherwise have implications for more than one state, such as 

those involving the movement of goods, funds, persons, intangibles, technology, 

vessels or aircraft.”

Because of this broad range, four characteristics can be pointed out. First,

IEL is obviously part of public international law. Treaties alone make this so. 

Second, IEL is intertwined with muncipal law. The balancing of economic treaty 

law with municipal law is important. Third, IEL requires multi-disciplinary 

thinking involving as it does not only economics but also political science, history, 

anthropology, geography,

335

336 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

etc. Fourth, empirical research is very important for understanding its operation.’

Important economic institutions.

After the Second World War, the economic advisers of the United States 

and of England led an effort to establish mechanisms which could avoid the 

repetition of the protectionist policies of the 1930s. The effort led to the Bretton 

Woods Conference of 1944. The conference had two main objectives: first, to 

advance the reduction of tariffs and other trade barriers, and second, to create a 

global framework designed to minimize economic conflicts. Out of this 

conference were bom the International Monetary Fund (IMF) whose function was 

to provide short-term financing to countries in balance of payments difficulties; 

the International Bank for Reconstruction and Development (World Bank) 

designed to provide long-term capital to support growth and development; and the 

International Trade Organization (ITO) which was intended to promote a liberal 

trading system by proscribing certain protectionist trade rules.

The intended function of the ITO was eventually taken over by the General 

Agreement on Tariff and Trade (GATT) and its successor the World Trade 

Organization (WTO). The GATT and the WTO are the most important trade 

oriented institutions. They shape domestic import and export laws which impact 

on international trade on goods and services.

GATT went through a series of modifications Rounds with the Uruguay 

Round of 1994 as the final one. The final agreement proposed the establishment of 

a World Trade Organization (WTO) which would oversee the operation of GATT 

and a new General Agreement on Trade and Services.

Key Principles of International Trade Law.

1. Agreed tariff levels. The GATT contains specified tariff levels for 

each state. Each state agrees not to raise tariff levels above those contained in the 

schedule. But these can be renegotiated.

'See Martin Dixon and Robert McCorquadale, CASES AND MATERIALS ON INTERNATIONAL LAW 485-524 Blackstone Press 

Limited, 1991.

CHAPTER 17

INTERNATIONAL ECONOMIC LAW

337

2. The most favored nation principle (MFN). The MFN clause embodies

the principle of non-discrimination. The principle means that any special treatment 

given to a product from one trading partner must be made available for like 

products originating from or destined for other contracting partners. In practice, 

this generally refers to tariff concessions.

3. Principle of national treatment. This prohibits discrimination between 

domestic producers and foreign producers. In practice, this means that once 

foreign producers have paid the proper border charges, no additional burdens may 

be imposed on foreign products.

4. Principle of tariffication. This principle prohibits the use of quotas on 

imports or exports and the use of licenses on importation or exportation. The 

purpose of the principle is to prevent the imposition of non-tariff barriers. But 

GATT provides for exceptions on a quantitative and temporary basis for balance 

of payments or infant industry reasons in favor of developing states.

Exceptions to key principles.

The GATT itself contains many exceptions to the key principles. Some of 

the exceptions are general in nature such as those referring to public morals, 

public health, currency protection, products of prison labor, national treasures of 

historic, artistic or archeological value, and protection of exhaustible natural 

resources. There are also security exceptions and regional trade exceptions. Of 

special significance for the Philippines are the exceptions for developing nations.

G.R. 118295, May 2,1997

WTO Recognizes Need to Protect Weak Economies

Upon the other hand, respondents maintain that the WTO itself 

has some built-in advantages to protect weak and developing 

economies, which comprise the vast majority of its members. Unlike 

in the UN where major states have permanent seats and veto powers 

in the Security Council, in the WTO, decisions are made on the basis 

of sovereign equality, with each member’s vote equal in weight to 

that of any other. There is no WTO equivalent of the UN Security 

Council.

INTRODUCTION TO PUBLIC INTERNATIONAL LAW

“WTO decides by consensus whenever possible, otherwise, 

decisions of the Ministerial Conference and the General Council shall 

be taken by the majority of the votes cast, except in cases of 

interpretation of the Agreement or waiver of the obligation of a 

member which would require three fourths vote. Amendments would 

require two thirds vote in general. Amendments to MFN provisions 

and the Amendments provision will require assent of all members. 

Any member may withdraw from the Agreement upon the expiration 

of six months from the date of notice of withdrawals.”

Hence, poor countries can protect their common interests more 

effectively through the WTO than through one-on-one negotiations 

with developed countries. Within the WTO, developing countries can 

form powerful blocs to push their economic agenda more decisively 

than outside the Organization. This is not merely a matter of practical 

alliances but a negotiating strategy rooted in law. Thus, the basic 

principles underlying the WTO Agreement recognize the need of 

developing countries like the Philippines to “share in the growth in 

international trade commensurate with the needs of their economic 

development.” These basic principles are found in the preamble of the 

WTO Agreement as follows:

“The Parties to this Agreement,

Recognizing that their relations in the field of trade and 

economic endeavor should be conducted with a view to raising 

standards of living, ensuring full employment and a large and steadily 

growing volume of real income and effective demand, and expanding 

the production of and trade in goods and services, while allowing for 

the optimal use of the world’s resources in accordance with the 

objective of sustainable development, seeking both to protect and 

preserve the environment and to enhance the means for doing so in a 

manner consistent with their respective needs and concerns at 

different levels of economic development.

Recognizing further that there is need for positive efforts 

designed to ensure that developing countries, and especially the least 

developed among them, secure a share in the growth in international 

trade commensurate with the needs of their economic development.

Being desirous of contributing to these objectives by entering 

into reciprocal and mutually advantageous arrangements directed to 

the substantial reduction of tariffs and other barriers to trade

CHAPTER 17

INTERNATIONAL ECONOMIC LAW

339

and to the elimination of discriminatory treatment in international 

trade relations.

Resolved, therefore, to develop an integrated, more viable and 

durable multilateral trading system encompassing the General 

Agreement on Tariffs and Trade, the results of past trade liberalization efforts, and all of the results of the Uruguay Round of Multilateral Trade Negotiations.

Determined to preserve the basic principles and to further the 

objectives underlying this multilateral trading system, . . (emphasis 

supplied.)

Specific WTO Provisos Protect Developing Countries

So too, the Solicitor General points out that pursuant to and 

consistent with the foregoing basic principles, the WTO Agreement 

grants developing countries a more lenient treatment, giving their 

domestic industries some protection from the rush of foreign 

competition. Thus, with respect to tariffs in general, preferential 

treatment is given to developing countries in terms of the amount of 

tariff reduction and the period within which the reduction is to be 

spread out. Specifically, GATT requires an average tariff reduction 

rate of 36% for developed countries to be effected within a period of 

six (6) years while developing countries — including the Philippines 

— are required to effect an average tariff reduction of only 24% 

within ten (10) years.

In respect to domestic subsidy, GATT requires developed 

countries to reduce domestic support to agricultural products by 20% 

over six (6) years, as compared to only 13% for developing countries 

to be effected within ten (10) years.

In regard to export subsidy for agricultural products, GATT 

requires developed countries to reduce their budgetary outlays for 

export subsidy by 36% and export volumes receiving export subsidy 

by 21% within a period of six (6) years. For developing countries, 

however, the reduction rate is only two-thirds of that prescribed for 

developed countries and a longer period of ten (10) years within 

which to effect such reduction.

Moreover, GATT itself has provided built-in protection from 

unfair foreign competition and trade practices including antidumping 

measures, countervailing measures and safeguards against import 

surges. Where local businesses are jeopardized by unfair foreign 

competition, the Philippines can avail of these measures.

340 INTRODUCTION TO PUBLIC INTERNATIONAL LAW

There is hardly therefore any basis for the statement that under the 

WTO, local industries and enterprises will all be wiped out and that 

Filipinos will be deprived of control of the economy. Quite the 

contrary, the weaker situations of developing nations like the 

Philippines have been taken into account; thus, there would be no 

basis to say that in joining the WTO, the respondents have gravely 

abused their discretion. True, they have made a bold decision to steer 

the ship of state into the yet uncharted sea of economic liberalization. 

But such decision cannot be set aside on the ground of grave abuse of 

discretion, simply because we disagree with it or simply because we 

believe only in other economic policies. As earlier stated, the Court in 

taking jurisdiction of this case will not pass upon the advantages and 

disadvantages of trade liberalization as an economic policy. It will

only perform its constitutional duty of determining whether the 

Senate committed grave abuse of discretion.

Dispute Resolution.

A Dispute Settlement Body (DSB) has been established by the WTO 

Agreement. It consists of the General Council of the WTO and operates under the 

Understanding on Rules and Procedures Governing the Settlement of Disputes 

1994 (DSU). Each state has a right to the establishment of a Panel. The DSU has 

also provided for a permanent Appellate Body, consisting of persons with 

recognized expertise in law, to handle appeals from a Panel decision.

Expanding Scope of International Economic Law.

The Uruguay Round of 1994 has expanded the scope of the multilateral 

trade regime. It now includes intellectual property, services, sanitary and 

physiosanitary measures and investment, as well as the strengthening of the rules 

on subsidies, countervailing duties and antidumping.

As can readily be seen, IEL has become a very specialized field. Most 

significantly too, it is affecting the sovereignty of states and their capacity to give 

force to national policy objectives.
